Computational biology has gained traction as an independent scientific discipline over the last years in South America. However, there is still a growing need for bioscientists, from different backgrounds, with different levels, to acquire programming skills, which could reduce the time from data to insights and bridge communication between life scientists and computer scientists. Python is a programming language extensively used in bioinformatics and data science, which is particularly suitable for beginners. Here, we describe the conception, organization, and implementation of the Brazilian Python Workshop for Biological Data. This workshop has been organized by graduate and undergraduate students and supported, mostly in administrative matters, by experienced faculty members since 2017. The workshop was conceived for teaching bioscientists, mainly students in Brazil, on how to program in a biological context. The goal of this article was to share our experience with the 2020 edition of the workshop in its virtual format due to the Coronavirus Disease 2019 (COVID-19) pandemic and to compare and contrast this year’s experience with the previous in-person editions. We described a hands-on and live coding workshop model for teaching introductory Python programming. We also highlighted the adaptations made from in-person to online format in 2020, the participants’ assessment of learning progression, and general workshop management. Lastly, we provided a summary and reflections from our personal experiences from the workshops of the last 4 years. Our takeaways included the benefits of the learning from learners’ feedback (LLF) that allowed us to improve the workshop in real time, in the short, and likely in the long term. We concluded that the Brazilian Python Workshop for Biological Data is a highly effective workshop model for teaching a programming language that allows bioscientists to go beyond an initial exploration of programming skills for data analysis in the medium to long term.

This article reports an investigation into undergraduate student experiences and views of a visual or ‘blocks' based programming language and its environment. An additional and central aspect of this enquiry is to substantiate the perceived degree of transferability of programming skills learnt within the visual environment to a typical mainstream textual language. Undergraduate students were given programming activities and examples covering four basic programming concepts based on the Sense programming language which is intended to simplify programming. Sense programming statements are represented by blocks which only fit together in ways that produce a meaningful syntactic outcome, which may lower the cognitive barrier to learning. Students were also presented with concepts represented using an equivalent textual construct and asked to consider their understanding of these based on the graphical cases. They were finally asked to complete a short online survey. This paper presents the programming activities, the survey and an analysis of the results.

The use of mean sea level as a surface of reference that might provide an independent control for geodetic leveling has been a long term goal arising from the classical analogy between the geoid as an equipotential surface and the surface assumed by a hypothetical undisturbed world ocean. The problems associated with this aim are now known to be vast, and are associated with the dynamics of the marine system, notably its response to meteorological forces, to variations in density and to the effects of basic circulation patterns. In consequence the mean sea level surface varies rapidly in both time and space. This identifies in fact a distinctive scientific discipline, coastal geodesy, in which contributions are required by both geodesists and oceanographers. It has come to be recognized that the coastal zone is a hazardous environment for all observational techniques concerned. On the one hand, the difficulties of measurement of coastal sea levels have only recently been understood; on the other hand, precise leveling procedures are now known to be influenced by the attraction of marine tides and by crustal deformation of tidal loading. Much of the data available for study are therefore inadequate and, moreover, it should be noted that long-time series are required. It is now possible to lay plans for both geodetic and oceanographic procedures to remedy these deficiencies in the long-term interests of the study.

Undergraduate students may be attracted to science and retained in science by engaging in laboratory research. Experience as an apprentice in a scientist's laboratory can be effective in this regard, but the pool of willing scientists is sometimes limited and sustained contact between students and faculty is sometimes minimal. We report outcomes from two different models of a summer neuroscience research program: an Apprenticeship Model (AM) in which individual students joined established research laboratories, and a Collaborative Learning Model (CLM) in which teams of students worked through a guided curriculum and then conducted independent experimentation. Assessed outcomes included attitudes toward science, attitudes toward neuroscience, confidence with neuroscience concepts, and confidence with science skills, measured via pre-, mid-, and postprogram surveys. Both models elevated attitudes toward neuroscience, confidence with neuroscience concepts, and confidence with science skills, but neither model altered attitudes toward science. Consistent with the CLM design emphasizing independent experimentation, only CLM participants reported elevated ability to design experiments. The present data comprise the first of five yearly analyses on this cohort of participants; long-term follow-up will determine whether the two program models are equally effective routes to research or other science-related careers for novice undergraduate neuroscientists.

In early 2020, Jain diaspora communities and organizations that had been painstakingly built over the past decades were faced with the far-reaching consequences of the COVID-19 pandemic and its concomitant restrictions. With the possibility of regular face-to-face contact and participation in recurring events—praying, eating, learning, and meditating together—severely limited in most places, organizations were compelled to make a choice. They either had to suspend their activities, leaving members to organize their religious activities on an individual or household basis, or pursue the continuation of some of their habitual activities in an online format, relying on their members’ motivation and technical skills. This study will explore how many Jain organizations in London took to digital media in its different forms to continue to engage with their members throughout 2020. Looking at a selection of websites and social media channels, it will examine online discourses that reveal the social and mental impact of the pandemic on Jains and the broader community, explore the relocation of activities to the digital realm, and assess participation in these activities. In doing so, this article will open a discussion on the long-term effects of this crisis-induced digital turn in Jain religious praxis, and in socio-cultural life in general.

Abstract In this paper, we present a theoretical foundation for a representation of a data set as a measure in a very large hierarchically parametrized family of positive measures, whose parameters can be computed explicitly (rather than estimated by optimization), and illustrate its applicability to a wide range of data types. The preprocessing step then consists of representing data sets as simple measures. The theoretical foundation consists of a dyadic product formula representation lemma, and a visualization theorem. We also define an additive multiscale noise model that can be used to sample from dyadic measures and a more general multiplicative multiscale noise model that can be used to perturb continuous functions, Borel measures, and dyadic measures. The first two results are based on theorems in [15, 3, 1]. The representation uses the very simple concept of a dyadic tree and hence is widely applicable, easily understood, and easily computed. Since the data sample is represented as a measure, subsequent analysis can exploit statistical and measure theoretic concepts and theories. Because the representation uses the very simple concept of a dyadic tree defined on the universe of a data set, and the parameters are simply and explicitly computable and easily interpretable and visualizable, we hope that this approach will be broadly useful to mathematicians, statisticians, and computer scientists who are intrigued by or involved in data science, including its mathematical foundations.

Learning outcomes After attempting the case, users are able to: analyse issues and problems faced by a call centre in Malaysia. Determine the root causes of the problems faced by call centre employees and generate alternative solutions to solve the problems faced by the company and to ensure the sustainability of the business. Case overview/synopsis This case was about the challenges faced by Daniel, the General Manager of an integrated security protection system company, Secure First (SF). Despite investing in the latest security technologies, conducting a major overhaul of the procedures, introducing an enhanced digital system at the call centre and providing training to the call agents, it was on the verge of losing its important long-term client due to its substandard performance. The client experienced major losses due to break-ins. After a thorough investigation, the problem surfaced in their call centre. Most of the staff were not familiar with the newly adopted system. The circumstances worsened when many of the call centre’s senior employees were tendering their resignations. The case discusses the aspect of employee satisfaction, staff performance that led to the turnover issue amongst employees in a call centre. The case explores what short-term and long-term strategies could Daniel suggest to change the call centre’s course to retain SF’s key account in times of desperation. Complexity academic level This case has a moderate level of difficulty and may be used in undergraduate students. Supplementary materials Teaching notes are available for educators only.

Abstract Studies show that retrieval practices such as homework assignments that are completed during the encoding phase of learning benefit knowledge acquisition and retention. In addition, desirable difficulties, which are strategies that intentionally create a greater challenge during initial learning to enhance encoding and retrieval pathways, also benefit learning long term. Our objective was to determine whether weekly homework questions intended to create desirable difficulties by requiring higher-order cognitive skills (HOCS) benefited students’ long-term retention of physiology concepts compared to questions designed to require lower-order cognitive skills (LOCS). Undergraduate students in a junior-level animal physiology course were presented information during weekly laboratory periods, and then required to complete retrieval practices in the form of online homework assignments 5 d after each lab. Homework questions were formatted per Bloom’s Taxonomy to require HOCS (i.e. level 4 or 5) or LOCS (i.e. level 1 or 2). Information retention was assessed the next week via performance on an in-class quiz and again at semesters’ end via performance on a final practical exam. We observed no differences in performance on the in-class quiz or final practical exam between students randomly assigned to complete homework with HOCS questions compared to LOCS questions. However, students that received homework with HOCS questions had decreased (P < 0.05) performance scores on 9 out of the 11 homework assignments compared to those receiving homework with LOCS questions. These findings indicate that desirable difficulties were not created by our HOCS homework questions because students receiving these more difficult retrieval practices did not achieve equal success on them. As a result, this attempt to create variations in cognitive demand did not enhance retention of knowledge in this study.

Computerized System

A computerized system is described, combining automatic collection of urine in short intervals (minutes) over long periods (days) and recordings of body temperature, MABP, and heart rate in chronically instrumented conscious dogs. During the studies the dogs are housed in metabolic cages. Indwelling catheters and electrical wires are connected to a specially designed swivel and directed out of the cage to the next room. Infusions, blood sampling, and monitoring can be performed from this room without disturbance to the dogs. Three examples of recordings are given. In one of these examples the sodium excretion patterns on 5 consecutive days under continuous saline infusion in one dog is evaluated. Urine was collected every 20 min. Sodium excretion showed cyclic variations. Fourier analysis exhibited 18-h periods and 4- to 8-h periods. The described system renders, e.g., coherent time series analysis possible for a variety of simultaneously recorded physiological variables and may thus acquire considerable importance for integrative physiology.

End Of Course Assessment

This study conducted in an EFL setting investigates students’ perception of the thesis proposal presentation in an online format due to safety concerns during the Covid-19 pandemic. Fifty-five students aged 20-22 years old, level B2-C1 in English, in their fourth year of a Business Informatics Bachelor’s programme at HSE University, Moscow, were surveyed regarding their end-of-course assessment experience, which involved a Skype online presentation, rather than the usual face-to-face presentation. Data were collected using a researcher-made questionnaire consisted of 3 sections and 12 items. A mixed-method approach using quantitative and qualitative data was employed. The findings indicate that emergency transition to the new format did not affect students’ satisfaction or results of the presentation. Overall, students were more than satisfied with the online format, and the results were similar, if not better, than in previous years. To minimise the disadvantages of this format, recommendations for teachers and students were offered. This study might offer new insight on the most appropriate and beneficial oral testing system for students and staff.
