A Compendium of Research, Tools, Structural Analysis, and Design for Bamboo Structures

Bamboo is known for its ability to grow at a high speed, with strong sustainability indicators and remarkable strength properties. However, despite these qualities, the practice of designing bamboo structures is still in its early stages in many regions. This paper aims to review the current approaches to structural analysis and design for bamboo structures as found in the existing literature. Through this comprehensive review, this study seeks to identify existing research gaps and areas that require further exploration. The limited design philosophy for bamboo structures can be attributed to the scarcity of studies on the characteristics and mechanics of bamboo material. These findings highlight the necessity for more comprehensive guidelines and standards to enhance the structural analysis and design of bamboo structures. This study identifies gaps in the following areas: lack of consideration for bamboo fiber distribution, lack of guidelines for load parameters specific to bamboo structures, inadequate coverage of bamboo culm connections, inadequate coverage on connection stiffness, limited scope on connection types, and species-specific limitations in standards.

Bilingual Signboards on Lombok: Approaches to Acquiring the Translation Equivalence

It is particularly intriguing to analyze the application of Baker's theory of translation equivalence through research on such brief texts as on signboard because it reveals a lot of interesting patterns. In order to make a signboard read in the least amount of time feasible and to get the word across to the reader in a more expedient manner, short phrases are frequently used. Texts taken from Lombok's newly emerging market for multilingual signboard served as the basis for this research's collection of data. This descriptive qualitative research aims to investigate the compatibility and applicability of the extended levels of Baker’s translation equivalence in the context of the collected data found on bilingual signboards at religious tourism sites on Lombok Island, particularly in relation to ethical, moral, and semiotic considerations. The study reveals the complex nature of translation equivalence in signboard, highlighting different levels such as word-level, grammatical, text-level, pragmatic, semiotic, and ethical equivalence. It offers practical insights for signboard designers, translators, and the tourism industry worldwide, providing essential information to unfamiliar tourists, contributing to their navigation and exploration of destinations. Additionally, the study underscores the significant role of signboard in tourism development, effective communication of information, intercultural understanding, and the growth of tourism in various destinations beyond Lombok.

Pedagogical approaches to health-related physical education (PE) in the context of digitalisation – a scoping review

ABSTRACT Introduction There are varied consequences of digital transformation processes within the fitness and health-related living environments of adolescents (e.g. increased physical activity through wearables, body dissatisfaction through social media) which could potentially provide fruitful health-related learning experiences within different pedagogical approaches to health in PE (e.g. biomedical vs. alternative, Mong and Standal, 2019, “Didactics of Health in Physical Education – a Review of Literature.” Physical Education and Sport Pedagogy 24 (5): 506–518. https://doi.org/10.1080/17408989.2019.1631270). However, concerns have been raised that the integration of digital media into health-related PE could reinforce biomedical approaches to health and lead, for example, to a focus on increasing fitness through technology. This one-sided focus would not be in line with the demands for a comprehensive health education. This paper aims to map the current trend of pedagogical approaches to health-related PE in the context of digitalisation and to identify typical learning goals against this background. Methods We conducted a scoping review based on the framework of Tricco et al. (2018, “PRISMA Extension for Scoping Reviews: Checklist and Explanation.” Annals of Internal Medicine 169 (7): 467–473. https://doi.org/10.7326/M18-0850). We searched nine databases using a search term covering three topic areas: digitalisation, health, and physical education. Considering the publication years from 2013 to 2023, we selected papers in a three-step process (title-, abstract-, and full-text-screening). In total, we included 103 empirical and theoretical papers in the analysis using qualitative content analysis (Kuckartz, 2019, “Qualitative Text Analysis: A Systematic Approach.” In Compendium for Early Career Researchers in Mathematics Education, edited by G. Kaiser and N. Presmeg, 181–197. Cham: Springer). To map the pedagogical approach to health, we applied the following main deductive categories: conceptualisation of health, paradigmatic approach to health and envisaged learning goals. To analyse learning goals with regard to digitalisation, we used the distinction between learning with and about digital media as a focus of analysis. Results The scoping review shows that most of the papers discussed a broad conceptualisation of health for PE by addressing biopsychosocial aspects of health. Many of the implications for health- and digitalisation-associated learning goals related to pre-reflective and functional-reflective learning goals in the area of learning with digital media. They mainly focused, from a pathogenic viewpoint, on how digital media can increase health-enhancing physical activity, affective determinants of health behaviour and health-related knowledge. Parts of these learning goals have already been empirically investigated. Only a few papers proposed critical-reflective learning goals in the area of learning about digital media, aiming at a socio-emancipatory engagement with digital media, health and society. No empirical study within the scoping review investigated the effectiveness of such critical health- and digitalisation-related PE. Discussion and conclusion In light of the results, it is important that future genuine pedagogical research about health- and digitalisation-related PE increasingly focuses on the development and empirical evaluation of theoretically sound concepts for PE that are in line with the educational demands of comprehensive – thus also critical and salutogenic – health and digital education.

Recent advances on reliability of FPGAs in a radiation environment

In recent years, SRAM-based Field-Programmable Gate Arrays (FPGAs) have seen a surge in deployment within aerospace applications. Despite their widespread use, these FPGAs, particularly their embedded Static Random Access Memory (SRAM) and user logic, exhibit a notable susceptibility to Single Event Upsets (SEU), a phenomenon leading to erroneous connections or routing discrepancies. This paper presents an exhaustive survey of fault-tolerance methodologies pertinent to SRAM-based FPGAs operating in radiation-intensive environments. Initially, we delineate the architecture of the SRAM-based FPGAs, elucidating the mechanisms underlying SEU occurrences and their subsequent malfunctions. This is followed by a detailed exploration of various strategies employed to assess the resilience of SRAM-based FPGAs against SEU-related disruptions, mainly including the Triple Module Redundancy (TMR) and the configuration scrubbing technology. Collectively, this survey aspires to function as an instructive compendium for engineers and researchers specializing in the development of fault-tolerance mechanisms for SRAM-based FPGAs, particularly in the context of aerospace applications.

Widespread Geographical Disparities in Phytoplankton Ecology Research in the Face of Climate Change: A Review

Climate change is a global threat that is better understood through global research spanning many regions, countries, and life-supporting ecosystems. This review focused on the bibliometric analysis of the distribution of a global research compendium on phytoplankton, an aquatic community that accounts for half of the carbon fixation in the global carbon cycle. A total of 716 primary research papers published in the immediate past decade (2012–2022) were reviewed. The articles were sampled from Web of Science and described field and laboratory experiments quantifying the impact of global climate change on phytoplankton from different climate zones (tropical, subtropical, temperate, subpolar, and polar) and ecosystems (freshwater, brackish, and marine). Analyses of these studies suggest that the bulk of the global research effort (80%) focused on high-latitude areas, and only a few (17%) were carried out in the tropics, largely led by four countries (Australia, Brazil, India, and Saudi Arabia), while Africa’s contribution was minuscule (<1%). In terms of ecosystems, the majority (76%) of the research was in marine waters, irrespective of the climate zone. Analyses of these studies also highlighted widespread disparities in phytoplankton research in tropical aquatic ecosystems, particularly in Africa. Strategic investment in terms of targeted funding, institutional networks, and partnerships between the global north and global south are necessary to increase phytoplankton research across different ecosystems in the tropics.

Unveiling innovative therapeutic strategies and future trajectories on stimuli-responsive drug delivery systems for targeted treatment of breast carcinoma.

This comprehensive review delineates the latest advancements in stimuli-responsive drug delivery systems engineered for the targeted treatment of breast carcinoma. The manuscript commences by introducing mammary carcinoma and the current therapeutic methodologies, underscoring the urgency for innovative therapeutic strategies. Subsequently, it elucidates the logic behind the employment of stimuli-responsive drug delivery systems, which promise targeted drug administration and the minimization of adverse reactions. The review proffers an in-depth analysis of diverse types of stimuli-responsive systems, including thermoresponsive, pH-responsive, and enzyme-responsive nanocarriers. The paramount importance of material choice, biocompatibility, and drug loading strategies in the design of these systems is accentuated. The review explores characterization methodologies for stimuli-responsive nanocarriers and probes preclinical evaluations of their efficacy, toxicity, pharmacokinetics, and biodistribution in mammary carcinoma models. Clinical applications of stimuli-responsive systems, ongoing clinical trials, the potential of combination therapies, and the utility of multifunctional nanocarriers for the co-delivery of assorted drugs and therapies are also discussed. The manuscript addresses the persistent challenge of drug resistance in mammary carcinoma and the potential of stimuli-responsive systems in surmounting it. Regulatory and safety considerations, including FDA guidelines and biocompatibility assessments, are outlined. The review concludes by spotlighting future trajectories and emergent technologies in stimuli-responsive drug delivery, focusing on pioneering approaches, advancements in nanotechnology, and personalized medicine considerations. This review aims to serve as a valuable compendium for researchers and clinicians interested in the development of efficacious and safe stimuli-responsive drug delivery systems for the treatment of breast carcinoma.

Innovation in publishing: Why we need systems for the review and curation of preprints

Watch VIDEO. The growing number of papers published openly as preprints on bioRxiv and medRxiv during recent years has highlighted how preprints can accelerate and democratise access to research. However, it has also shown the need for systems of review that help readers easily assess the quality of new findings. A number of groups are now working to openly peer-review preprints, making them more useful for authors, readers, the broader research community and the general public. Some of these models are also taking advantage of the open nature of preprints to enable researchers from groups traditionally underrepresented in science to participate in public review, sharing their expertise and perspectives with authors, readers and others who engage with preprints. These groups include, for example: ASAPbio–SciELO Preprints crowd review, Biophysics Colab, the Novel Coronavirus Research Compendium, and eLife, which officially launched a new model for publishing in January 2023. eLife’s new model eliminates accept/reject decisions after peer review and focuses instead on providing quality public reviews and assessments. The output is a Reviewed Preprint, which combines the immediacy and openness of preprints with the scrutiny of peer review by experts. This model feeds into eLife’s overarching ‘publish, review, curate’ mission that puts preprints first. In this presentation, we will highlight the work of eLife in reviewing and curating preprints, and discuss why transforming preprints into reviewed preprints will have significant benefits for scientists and science more broadly.

A longitudinal examination of parallel growth and reciprocal changes in teacher-student relationships and academic achievement.

There is a compendium of research to support the premise that positive teacher-student relationships (TSR) set the stage for children's success via classroom engagement, social functioning, and academic skills development. Although studies have demonstrated reciprocal associations between TSR and academic achievement, inferences that stem from prior study results are limited due to methodological designs that fall short in capturing directionality in developmental change processes. To address gaps in the literature and improve our understanding of the complex associations between TSR and academic achievement, we analyzed the codevelopment of TSR and achievement in reading and mathematics using dual change score models (DCSM), a type of latent change score model, focusing on the associations between longitudinal trajectories of TSR-achievement pairs and on the reciprocal prediction of latent changes between each wave of measurement. We examined data from a large-scale, nationally representative study (Early Childhood Longitudinal Study Kindergarten Cohort of 2010-2011). Results of our DCSM, contrary to prior findings, demonstrate that variability in the ratings of TSR did not predict subsequent latent changes in reading or mathematics achievement. Likewise, the variability in achievement scores did not predict subsequent latent changes in ratings of TSR. Limitations and future directions for research are discussed.

Rang: Reconstructing reproducible R computational environments.

A complete declarative description of the computational environment is usually missing when researchers share their materials. Without such description, software obsolescence and missing system components can jeopardize computational reproducibility in the future, even when data and computer code are available. The R package rang is a complete solution for generating the declarative description for other researchers to automatically reconstruct the computational environment at a specific time point. The reconstruction process, based on Docker, has been tested for R code as old as 2001. The declarative description generated by rang satisfies the definition of a reproducible research compendium and can be shared as such. In this contribution, we show how rang can be used to make otherwise unexecutable code, spanning fields such as computational social science and bioinformatics, executable again. We also provide instructions on how to use rang to construct reproducible and shareable research compendia of current research. The package is currently available from CRAN (https://cran.r-project.org/web/packages/rang/index.html) and GitHub (https://github.com/chainsawriot/rang).

Making use of apex predator sample collections: an integrated workflow for quality assured sample processing, analysis and digital sample freezing of archived samples

Using monitoring data from apex predators for chemicals risk assessment can provide important information on bioaccumulating as well as biomagnifying chemicals in food webs. A survey among European institutions involved in chemical risk assessment on their experiences with apex predator data in chemical risk assessment revealed great interest in using such data. However, the respondents indicated that constraints were related to expected high costs, lack of standardisation and harmonised quality criteria for exposure assessment, data access, and regulatory acceptance/application. During the Life APEX project, we demonstrated that European sample collections (i.e. environmental specimen banks (ESBs), research collection (RCs), natural history museums (NHMs)) archive a large variety of biological samples that can be readily used for chemical analysis once appropriate quality assurance/control (QA/QC) measures have been developed and implemented. We therefore issued a second survey on sampling, processing and archiving procedures in European sample collections to derive key quality QA/QC criteria for chemical analysis. The survey revealed great differences in QA/QC measures between ESBs, NHMs and RCs. Whereas basic information such as sampling location, date and biometric data were mostly available across institutions, protocols to accompany the sampling strategy with respect to chemical analysis were only available for ESBs. For RCs, the applied QA/QC measures vary with the respective research question, whereas NHMs are generally less aware of e.g. chemical cross-contamination issues. Based on the survey we derived key indicators for assessing the quality of biota samples that can be easily implemented in online databases. Furthermore, we provide a QA/QC workflow not only for sampling and processing but also for the chemical analysis of biota samples. We focussed on comprehensive analytical techniques such as non-target screening and provided insights into subsequent storage of high-resolution chromatograms in online databases (i.e. digital sample freezing platform) to ultimately support chemicals risk assessment.

MAINSTREAMING METADATA INTO RESEARCH WORKFLOWS TO ADVANCE REPRODUCIBILITY AND OPEN GEOGRAPHIC INFORMATION SCIENCE

Abstract. Reproducible open science with FAIR data sharing principles requires research to be disseminated with open data and standardised metadata. Researchers in the geographic sciences may benefit from authoring and maintaining metadata from the earliest phases of the research life cycle, rather than waiting until the data dissemination phase. Fully open and reproducible research should be conducted within a version-controlled executable research compendium with registered pre-analysis plans, and may also involve research proposals, data management plans, and protocols for research with human subjects. We review metadata standards and research documentation needs through each phase of the research process to distil a list of features for software to support a metadata-rich open research life cycle. The review is based on open science and reproducibility literature and on our own work developing a template research compendium for conducting reproduction and replication studies. We then review available open source geographic metadata software against these requirements, finding each software program to offer a partial solution. We conclude with a vision for software-supported metadata-rich open research practices intended to reduce redundancies in open research work while expanding transparency and reproducibility in geographic research.

The role of testosterone in men's health: is it time for a new approach?

Because of many unanswered questions regarding men's health, a literature review was performed to better understand the role of testosterone and testosterone replacement therapy (TRT) in the management of hypogonadism and aging related prostate gland diseases (ARPGD) including prostate cancer (PCa) and benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). The PubMed database was screened for pertinent peer reviewed articles published during the last four decades that culminated in the positions and recommendations in this paper. Hypogonadism seriously impacts men's health, and the diagnosis remains controversial. The incidence of ARPGD is projected to increase worldwide and treatment still has significant limitations. There is compelling evidence that lower, not higher, testosterone levels trigger the development of PCa and BPH through androgen receptor over-expression. TRT was found to be safe and effective in treating hypogonadism including in PCa survivors and those harboring PCa. There is also evidence that TRT might reduce the incidence and prevalence of ARPGD. This review synthesizes a wide-ranging compendium of basic science and clinical research that strongly encourages altering the present approach to diagnosing and treating men with hypogonadism and ARPGD. These findings underscore the importance of avoiding significant testosterone decline and support the use of TRT. Ten recommendations are offered as a framework for the way forward. It is now time for clinicians, payers, researchers, funding agencies, professional associations, and patient advocacy groups to embrace this new paradigm to increase longevity and improve the quality of life.

Лингвистическая идентификация автора и фальсификация идентичности в сети

Research on modern virtual communication focuses on human communicative behaviour in social networks. For the purposes of successful biometric expertise, linguistic personology is chosen as the most reliable approach. As a complex autonomous interdisciplinary synergistic paradigm, and as a research compendium that uses a wide variety of approaches and methods of modern linguistics, linguistic personology is designed to study the variety of human speech behaviour manifested in the speech of a person. It is also used to identify "bright diagnostic spots" that characterize the verbal messages of any individual linguistic personality in social networks with the purpose of its precise identification. Personality identification, enhanced by linguistic personology methods, is presented as efficient methodology, since it creates conditions for reliability and trust in the process of information exchange, and is based on truthfulness and legitimacy. The compendium of sciences for analyzing speech behaviour and for describing the speech repertoire of the virtual personality is based, on the one hand, on the study of formal discursive characteristics based on style (style-based features), while, on the other, it relies on the study of informal content characteristics (content-based features).

Competition and Integration of US Health Systems in the Post-COVID-19 New Normal: Cross-sectional Survey

BackgroundHow do health systems in the United States view the concept of merger and acquisition (M&A) in a post-COVID 19 “new normal”? How do new entrants to the market and incumbents influence horizontal and vertical integration of health systems? Traditionally, it has been argued that M&A activity is designed to reduce inequities in the market, shift toward value-based care, or enhance the number and quality of health care offerings in a given market. However, the recent history of M&A activity has yielded fewer noble results. As might be expected, the smaller the geographical region in which M&A activity is pursued, the higher the likelihood that monopolistic tendencies will result.ObjectiveWe focused on three types of competition perceptions, external environment uncertainty–related competition, technology disruption–driven competition, and customer service–driven competition, and two integration plans, vertical integration and horizontal integration. We examined (1) how health system characteristics help discern competition perceptions and integration decisions, and (2) how environment-, technology-, and service-driven competition aspects influence vertical and horizontal integration among US health systems in the post-COVID-19 new normal.MethodsWe used data for this study collected through a consultant from a robust group of health system chief executive officers (CEOs) across the United States from February to March 2021. Among the 625 CEOs, 135 (21.6%) responded to our survey. We considered competition and integration aspects from the literature and ratified them via expert consensus. We collected secondary data from the Agency for Healthcare Research and Quality (AHRQ) Compendium of the US Health Systems, leading to a matched data set for 124 health systems. We used inferential statistical comparisons to assess differences across health systems regarding competition and integration, and we used ordered logit estimations to relate competition and integration.ResultsHealth systems generally have a high level of the four types of competition perceptions, with the greatest concern being technology disruption–driven competition rather than environment uncertainty–related competition and customer service–driven competition. The first set of estimation results showed that size, teaching status, revenue, and uncompensated care burden are the main contingent factors influencing the three competition perceptions. The second set of estimation results revealed the relationships between different competition perceptions and integration plans. For vertical integration, environment uncertainty–related competition had a significant positive influence (P<.001), while the influence of technology disruption–driven competition was significant but negative (P<.001). The influence of customer service–driven competition on vertical integration was not evident. For horizontal integration, the results were similar for environment uncertainty–related competition and technology disruption–driven competition; however, the significance of technology disruption–driven competition was weak (P=.05). The influence of customer service–driven competition in the combined model was significant and negative (P<.001).ConclusionsCompetition-driven integration has subtle influences across health systems. Environment uncertainty–related competition is a significant factor, with underlying contingent factors such as revenue concerns and leadership as the leading causes of integration plans. However, technology disruption may hinder integrations. Undoubtedly, small- and low-revenue health systems facing a high level of competition are likely to merge to navigate the health care business successfully. This trend should be a focus of policy to avoid monopolistic markets.

Developing a Statewide Research Compendium: Key Points and Steps for Success.

Engaging clinical nurses in nursing research requires value for the nurses and a structured process. One way to involve nurses in research is through development of a research compendium. A professional development specialist can lead the creation of a research compendium. Identifying key stakeholders, developing a technologic infrastructure, piloting the compendium, gaining feedback, and identifying outcomes that will be evaluated are key.

Curating the Evidence About COVID-19 for Frontline Public Health and Clinical Care: The Novel Coronavirus Research Compendium.

The public health crisis created by the COVID-19 pandemic has spurred a deluge of scientific research aimed at informing the public health and medical response to the pandemic. However, early in the pandemic, those working in frontline public health and clinical care had insufficient time to parse the rapidly evolving evidence and use it for decision-making. Academics in public health and medicine were well-placed to translate the evidence for use by frontline clinicians and public health practitioners. The Novel Coronavirus Research Compendium (NCRC), a group of >60 faculty and trainees across the United States, formed in March 2020 with the goal to quickly triage and review the large volume of preprints and peer-reviewed publications on SARS-CoV-2 and COVID-19 and summarize the most important, novel evidence to inform pandemic response. From April 6 through December 31, 2020, NCRC teams screened 54 192 peer-reviewed articles and preprints, of which 527 were selected for review and uploaded to the NCRC website for public consumption. Most articles were peer-reviewed publications (n = 395, 75.0%), published in 102 journals; 25.1% (n = 132) of articles reviewed were preprints. The NCRC is a successful model of how academics translate scientific knowledge for practitioners and help build capacity for this work among students. This approach could be used for health problems beyond COVID-19, but the effort is resource intensive and may not be sustainable in the long term.
