Highly cited papers showcase high-quality research and encompass significant themes in the field. This study examined a total of 435 highly cited papers based on Essential Citation Indicators in the Web of Science (WoS) category of sport sciences with a bibliometric method. In particular, the bibliometric indicators of the highly cited papers including publication venues, authors, countries, institutions, and the top cited publications were presented and analyzed in detail. An Abstract corpus was constructed to help identify the most frequently explored topics. VOSviewer was employed to visualize the co-occurrence networks of keywords. The study revealed the trending information of important contributors at the levels of journals, authors, countries, and institutes. The top cited publications can be grouped into three categories: guidelines, recommendations based on systematic reviews, and evaluations. The most frequently explored topics based on the Abstract corpus and the most frequently used keywords from VOSviewer mapping overlap to a great extent. Specifically, topics such as meta-analysis, systematic review, sport-related concussion, sedentary behavior, football, rehabilitation, and osteoarthritis are among the most frequently mentioned. The results provide the most updated publication characteristics and hot topics of highly cited papers in sport sciences and offer insights for academic researchers in future research.

In this brief communication, we highlight several critical inaccuracies in the paper entitled "A novel methodology for a time-delayed controller to prevent nonlinear system oscillations," identified by the DOI: 10.1177/14613484231195276. The core of the non-perturbative approach discussed in this paper is the introduction of a trial solution with an indeterminate nonlinear frequency. We elucidate the technical missteps and provide necessary corrections. The scrutinized article presents ample opportunities for enhancement, and we propose several amendments. Additionally, we reveal that the numerical outcomes showcased in the mentioned paper expose deficiencies in the proposed approximate solution. With the amendments implemented herein, a more precise numerical solution is achieved. [ABSTRACT FROM AUTHOR]

Compared to the abundant generic research on technologies and education, few studies focus on the scope of whether the technologies used meet the expectations set forth in international reports and to what extent technology contributes to transforming educational practice. Our objective was to identify and analyze the characteristics of educational practices that are being developed in higher education and to assess the value that technology brings to educational practice. We conducted a systematic review of academic papers published in scientific journals: a corpus of 1,207 articles from six journals included in indexed databases (JCR and SJR), selected using Google Scholar Metrics. According to the various records screened, the study we present is based on 49 articles, published between 2018 and 2019. We conclude that beyond their reproducible, enriching, or transformative nature, most of the articles analyzed address the improvement of students' performance, engagement, or self-perception, in which they positively value the experience of learning mediated by digital technology, although they do not have an impact on the transformative value.

The research process of authoring a review paper constitutes a uniquely important context for interrogating tacit premises and presuppositions, especially when the review aspires to synthesize a methodologically diverse field of research. This article presents a reflexive recounting of a research experience with mixed methods team-based review paper authorship, showing how the function of a review paper may be differently conceptualized by scholars situated in methodological traditions that place their emphasis on drawing-together knowledge about the social world versus those situated in methodological traditions whose primary aim is to unpack accepted categories. The analysis thus offers insights into dimensions of methodological difference as they operate in practice, while underscoring the significance of reflexivity in the review paper context for purposes of advancing meaningfully inclusive maps of an intellectual community's self-understanding(s).

Tissue engineering (TE) is the multi-disciplinary approach to building 3D human tissue equivalents in the laboratory. The advancement of medical sciences and allied scientific disciplines have aspired to engineer human tissues for three decades. To date there is limited use of TE tissues/organs as replacement body parts in humans. This position paper outlines advances in engineering of specific tissues and organs with tissue-specific challenges. This paper outlines the technologies most successful for engineering tissues and key areas of advancement. [ABSTRACT FROM AUTHOR]

Cerebral autoregulation (CA) refers to the control of cerebral tissue blood flow (CBF) in response to changes in perfusion pressure. Due to the challenges of measuring intracranial pressure, CA is often described as the relationship between mean arterial pressure (MAP) and CBF. Dynamic CA (dCA) can be assessed using multiple techniques, with transfer function analysis (TFA) being the most common. A 2016 white paper by members of an international Cerebrovascular Research Network (CARNet) that is focused on CA strove to improve TFA standardization by way of introducing data acquisition, analysis, and reporting guidelines. Since then, additional evidence has allowed for the improvement and refinement of the original recommendations, as well as for the inclusion of new guidelines to reflect recent advances in the field. This second edition of the white paper contains more robust, evidence-based recommendations, which have been expanded to address current streams of inquiry, including optimizing MAP variability, acquiring CBF estimates from alternative methods, estimating alternative dCA metrics, and incorporating dCA quantification into clinical trials. Implementation of these new and revised recommendations is important to improve the reliability and reproducibility of dCA studies, and to facilitate inter-institutional collaboration and the comparison of results between studies.

This paper analyses how a state produces new internal borders. It selected 1668 newspaper articles on the COVID-19 internal bordering case in Slovakia to answer this question. These articles were then analysed using the thematic trajectory analysis (TTA) through the conceptual prism of structurationism. The results suggest states apply methods during the production of internal borders similar to those used during the (re-)production of an international border. In particular, it shows the application of a military-testing nexus and economic tools to ensure compliance with the new border. Results also revealed that such a border is heavily dependent on popular support for the government and open to re-negotiations by relevant societal groups. From the border production perspective, this study offers a preliminary step into the area of internal borders imposed on a generally homogenous population, especially regarding the borders produced under COVID-19 conditions.

Background: Harmful Alcohol use is frequent among opioid dependents patients undergoing agonist maintenance treatment. The objective assessment of harmful alcohol use can be done using laboratory measures of serum biomarkers. For community-based patients, there is often a requirement of an alternative method due to lack of onsite laboratory services. The aim of the study was to examine filter paper as a matrix to measure serum biomarkers of harmful alcohol use. Methods: The initial phase involved standardization of the filter-paper-based assay. Conditions were optimised for extraction and estimation of alcohol biomarkers (Aspartate Aminotransferase; AST, Alanine Aminotransferase; ALT, Gamma Glutamyl transferase; GGT and Carbohydrate Deficient Transferrin; CDT) from the filter paper. For clinical validation, serum samples were collected from community clinics. Biomarker levels obtained from both the methods were correlated using linear regression analysis. Limits of agreement between the two methods was estimated using the Intraclass Correlation Coefficient (ICC). Results: The extraction of enzymes (AST, ALT and GGT) from filter paper was carried out using the substrate buffer available with the reagent kit (Randox, UK). CDT was readily extracted from filter paper using deionised water. Serum biomarker levels measured from samples collected from community clinics correlated well with filter paper extracted levels (ICC 0.97-0.99). More than 90% of alcohol biomarker levels were recovered from the filter paper matrix using this method. Conclusion: Filter paper has the potential to be used as a matrix to objectively measure alcohol biomarkers among opioid-dependent patients from community settings lacking onsite laboratory facilities.

In this study, carbon papers and aerogels were prepared from chitosan and graphene layers with aldehydic edge functional groups (G-CHO) able to form chemical bonds with chitosan and thus to form a crosslinked network. A high surface area graphite was edge functionalized with hydroxyl groups (G-OH) through the reaction with KOH. G-CHO, with 4.5 mmol/g of functional group, was prepared from G-OH by means of the Reimer-Tieman reaction. Characterization of the graphitic materials was performed with elemental analysis, titration, X-ray analysis, Raman spectroscopy and by estimating their Hansen solubility parameters. CS and G-CHO were mixed with mortar and pestle and carbon papers and aerogels were obtained from a stable acidic water suspension through casting and liophilization, respectively. Free standing and foldable carbon papers and monolithic aerogels based on a continuous covalent network between G-CHO and CS were prepared. G-CHO, which had about 22 stacked layers, was extensively exfoliated in the carbon paper, as confirmed by the absence of the 002 reflection of the graphitic crystallites in the XRD pattern. Carbon paper was found to be resistant to solvents and to be stable for pH ⩾ 7. Composites revealed electrical conductivity. The covalent network between the graphene layers and CS, suggested by the IR findings, accounts for these results. This work demonstrates the effectiveness of a continuous covalent network between chitosan and graphene layers edge functionalized with tailor made functional groups for the preparation of carbon papers and aerogels and paves the way for the scale up of such a type of composites.

Previous research is inconclusive regarding the effects of paper and web surveys on response burdens. We conducted an establishment survey with random assignment to paper and web modes to examine this issue. We compare how the actual and perceived response burdens differ when respondents complete a survey in the paper mode, in the web mode and when they are allowed to choose between the two modes. Our results show that in the web mode, respondents have a lower estimated time to complete the questionnaire, while we do not find differences between paper and the web on the perceived response time and perceived burden. Even though the response burden in the web mode is lower, our study finds no evidence of an increased response burden when moving an establishment survey from paper to the web.

Paper-based visual analogue scale (VAS) items were developed 100 years ago. Although they gained great popularity in clinical and medical research for assessing pain, they have been scarcely applied in other areas of psychological research for several decades. However, since the beginning of digitization, VAS have attracted growing interest among researchers for carrying out computerized and paper-based data assessments. In the present study, we investigated the research question "Which different design characteristics of paper-based VAS items are preferred by women and men?" Based on a sample of 115 participants (68 female), our results revealed that the respondents preferred a paper-based VAS item with a horizontal, 8-cm long, 3 DTP ("desktop publishing point") wide, black line, with flat line endpoints, and the ascending numerical anchors "0" and "10", both for women and men. Although we did not identify any gender difference in these characteristics, our findings uncovered clear preferences on how to design paper-based VAS items. [ABSTRACT FROM AUTHOR]

In recent years, the problem caused by waste disposable paper cups (WDPCs) has became a topic of great concern to scientists, and commercial companies have also begun to take an interest in developing processes for tackling the issue. In this review, the inherent problems and social barriers during the recycling of WDPCs are described. This review presents the major conclusions of previously published works focused on the utilisation of WDPCs for material and energy purposes. The commercial utilisation of WDPCs is also described. Some suggestions for better recycling of WDPCs are given in the final part of this work. [ABSTRACT FROM AUTHOR]

The application of big data, radiomics, machine learning, and artificial intelligence (AI) algorithms in radiology requires access to large data sets containing personal health information. Because machine learning projects often require collaboration between different sites or data transfer to a third party, precautions are required to safeguard patient privacy. Safety measures are required to prevent inadvertent access to and transfer of identifiable information. The Canadian Association of Radiologists (CAR) is the national voice of radiology committed to promoting the highest standards in patient-centered imaging, lifelong learning, and research. The CAR has created an AI Ethical and Legal standing committee with the mandate to guide the medical imaging community in terms of best practices in data management, access to health care data, de-identification, and accountability practices. Part 2 of this article will inform CAR members on the practical aspects of medical imaging de-identification, strengths and limitations of de-identification approaches, list of de-identification software and tools available, and perspectives on future directions.

It is a growing concern that outcomes of neuroimaging studies often cannot be replicated. To counteract this, the magnetic resonance (MR) neuroimaging community has promoted acquisition standards and created data sharing platforms, based on a consensus on how to organize and share MR neuroimaging data. Here, we take a similar approach to positron emission tomography (PET) data. To facilitate comparison of findings across studies, we first recommend publication standards for tracer characteristics, image acquisition, image preprocessing, and outcome estimation for PET neuroimaging data. The co-authors of this paper, representing more than 25 PET centers worldwide, voted to classify information as mandatory, recommended, or optional. Second, we describe a framework to facilitate data archiving and data sharing within and across centers. Because of the high cost of PET neuroimaging studies, sample sizes tend to be small and relatively few sites worldwide have the required multidisciplinary expertise to properly conduct and analyze PET studies. Data sharing will make it easier to combine datasets from different centers to achieve larger sample sizes and stronger statistical power to test hypotheses. The combining of datasets from different centers may be enhanced by adoption of a common set of best practices in data acquisition and analysis. [ABSTRACT FROM AUTHOR]

Objective The purpose of the present research is to establish measurement equivalence and test differences in reliability between computerized and pencil-and-paper-based tests of spatial cognition. Background Researchers have increasingly adopted computerized test formats, but few attempt to establish equivalence for computer-based and paper-based tests. The mixed results in the literature on the test mode effect, which occurs when performance differs as a function of test medium, highlight the need to test for, instead of assume, measurement equivalence. One domain that has been increasingly computerized and is thus in need of tests of measurement equivalence across test mode is spatial cognition. Method In the present study, 244 undergraduate students completed two measures of spatial ability (i.e., spatial visualization and cross-sectioning) in either computer- or paper-and-pencil-based format. Results Measurement equivalence was not supported across computer-based and paper-based formats for either spatial test. The results also indicated that test administration type affected the types of errors made on the spatial visualization task, which further highlights the conceptual differences between test mediums. Paper-based tests also demonstrated increased reliability when compared with computerized versions of the tests. Conclusion The results of the measurement equivalence tests caution against treating computer- and paper-based versions of spatial measures as equivalent. We encourage subsequent work to demonstrate test mode equivalence prior to the utilization of spatial measures because current evidence suggests they may not reliably capture the same construct. Application The assessment of test type differences may influence the medium in which spatial cognition tests are administered. [ABSTRACT FROM AUTHOR]

The folded paper-size illusion is as easy to demonstrate as it is powerful in generating insights into perceptual processing: First take two A4 sheets of paper, one original sized, another halved by folding, then compare them in terms of area size by centering the halved sheet on the center of the original one! We perceive the larger sheet as far less than double (i.e., 100%) the size of the small one, typically only being about two thirds larger--this illusion is preserved by rotating the inner sheet and even by aligning it to one or two sides, but is dissolved by aligning both sheets to three sides, here documented by 88 participants' data. A potential explanation might be the general incapability of accurately comparing more than one geometrical dimension at once--in everyday life, we solve this perceptual-cognitive bottleneck by reducing the complexity of such a task via aligning parts with same lengths.

In this paper, we outline our qualitative protocol for the largest, independent, mixed-method, evaluation of the High Volume-Low Complexity Surgical Hubs programme in England – The MEASURE study. In addition to serving as a protocol paper, we outline the key methodological considerations and adaptations that are needed when designing big qualitative studies – complex (multi-site, multi-stakeholder), multi-method (e.g. interviews, observations, documents) qualitative research involving a large number of participations (n = 100+). This paper expands on our previous methodological work, where we used our experience of undertaking a big qualitative study as part of a mixed-method evaluation of a national emergency care-based initiative, to outline the methodological considerations and uncertainties for designing and analysing "big" qualitative studies. In this paper, we put these considerations into practice by providing a transparent account of our qualitative study design. The methodological reflections which we present are centred around the areas where we feel there is the most uncertainty for big qualitative research: study design, sampling (of case sites and stakeholders) and analysis. Underpinning this uncertainty are broader challenges which utilising this approach incite. Namely, that striving for both breadth (national-level insights) and depth (local variation and context), challenges paradigmatic norms and expectations and forces either methodological innovation, or the adaption of existing qualitative methods. We hope this paper provides transparency and insight into an area of qualitative research which has, potentially due to a perception of "safety in numbers" been inherently trusted and rarely scrutinised. Ultimately, we hope that by providing a transparent account of our study design and the challenges we have faced that we continue to encourage discussion and innovation in this evolving area of qualitative research.

This paper draws together critical learnings from diverse qualitative health research projects in Australia that sought to shift power and focus on the strengths and expertise of people with lived experience who are involved as co-researchers. These projects have included exploring and challenging identities, understanding experiences in treatment programs, critiquing and designing/re-designing services, and sharing experiences with the wider community in novel and innovative ways. Lived experiences included alcohol and other drug dependency, mental health, domestic, family or sexual violence, and living with HIV. This paper provides important learnings and actions about partnering with co-researchers with lived experience. In this paper we draw on a process of reflective discussions that occurred over six months with fortnightly online meetings between co-researchers, including co-authors with lived experience external to academia and university-based researchers, some of whom also have lived-experience that intersects with their research. From this, we distilled key learnings across seven themes: (1) the ethics of ethics, which highlights a need for constant reflection on the ethical issues in co-research; (2) recruiting co-researchers, which focuses on ensuring and integrating a diversity of voices; (3) creating safety for all, which must be a priority of engagement and support self-determination; (4) supporting different ways of partnering, which emphasises the need for diverse roles and ways to contribute on research teams; (5) capacity building and training, which requires ongoing evaluation of needs and tailored responses; (6) positioning, which highlights the need to transition from the idea of vulnerability to a strengths-based perspective of lived experience; and (7) power plays, reflecting the need to disrupt the dynamics and established hierarchies of privileging certain forms of knowledge and expertise. The paper includes recommendations for action against these seven themes. [ABSTRACT FROM AUTHOR]

Regarding debates over researcher insider/outsider positionalities in the field of migration studies, many scholars have proposed various explanations. Some scholars studying migrant populations note that migrant scholars who share identities such as nationality, language, religion, race, ethnicity etc. with their study participants are usually perceived as insiders. Other scholars, however, contend that dynamics of insider/outsider positionalities are situationally shaped during researcher-participant interactions in fieldwork. There is now wide consensus among many scholars that shared social identities between researchers and study participants do not automatically position researchers as insiders. Drawing on secondary literature and my fieldwork encounters, this paper contributes to these debates by proposing typologies for migration researchers to use as analytical tools. The three typologies that map out insider/outsider dynamics during researcher-participant encounters in fieldwork are presuming ethnic insiderness/outsiderness, presuming national insiderness/outsiderness and the indeterminate fieldwork context. This paper argues that researchers' insider/outsider positionalities should not be viewed as pre-determined or fixed formations but as uncertain and situationally constituted. I further argue that migration researchers should not enter the fieldwork with an assumption of automatic insiderness or outsiderness but that they need to view their insider or outsider positionalities as emerging during encounters with research participants.

This scoping review offers insight into researcher well-being when working with sensitive and traumatic topics in a qualitative research context. The study identified existing empirical research concerning researcher well-being and mental health. The databases included SSCI, ASSIA < IBISS, Scopus, Social Policy and Practice, PsycInfo, Social Science Database/Social Science Premium Collection (Proquest), and Open Grey. An international search was conducted, with no time constraints on publication dates to gather as wide a selection as possible. 55 papers met the criteria. We found that the terminology used within the papers was not consistent which necessitated grouping the (self-) reflection/reflexive practices researchers used and categorizing them under the umbrella term SRR practices. The research questions were: 1. Which disciplines or fields are conducting SRR practices on sensitive topics? 2. What SRR practices do researchers employ in the context of sensitive research? 3. What were the self-reported outcomes from using SRR practices as a tool of researchers working on sensitive research? A key finding of the scoping review is that many researchers who work on sensitive topics feel unprepared and receive little or no training or support for SRR practices. This poses particular challenges for early career researchers. We also identified that qualitative researchers have developed a range of SRR practices to manage the emotional impact of their sensitive research work. Many authors of the scoped papers stress the importance of peer-support as well as formal and informal debriefing meetings. Another key SRR practice discussed by many researchers is reflexive journaling. Our scoping review suggests that if it is combined with other activities, self-reflexive journaling can be an excellent way to acknowledge and assess the emotional impact of sensitive research.

The impedance matching is essential in producing high-intensity acoustic waves. This paper studies the impedance calculation methods of modulators and double-chamber Helmholtz resonators based on fluid mechanics, aeroacoustics, and electro-acoustic analogy principles. The results: ① The impedance expression of the resonators is derived. ② The impedance variation law of the chamber volume, the stator size, the air supply pressure, the air supply flow, and the working frequency is calculated. ③ The impedance-matching design scheme of the two-chamber Helmholtz low frequency and high acoustic intensity generator is given. Based on the experimental results of the high acoustic intensity generating device that the author has manufactured in the closed space, the correctness of the impedance calculation and matching design scheme in this paper is verified. This method has guiding significance for the design of high-intensity acoustic generating devices in confined space. [ABSTRACT FROM AUTHOR]

The transverse leaf spring (TLS) suspensions are a promising option for van vehicles due to their high load-carrying capacity and excellent handling stability. However, its ride comfort remains a major challenge. This paper investigates and compares the effects of semi-active and active control strategies to enhance the ride comfort of TLS suspensions. Firstly, a four-degree-of-freedom (4-DOF) half-car model and a multi-body dynamics (MBD) model of the TLS suspensions are established. The MBD model has higher accuracy and can describe the medium and high frequency characteristics of the TLS suspensions, such as the suspension offset frequency and the frequency response function of the body vertical acceleration (BVA). Therefore, based on the MBD half-car model with TLS suspensions, this paper proposes an optimal fuzzy PID active control strategy considering the left and right suspension coupling. The optimization objectives are the BVA, the left and right suspensions dynamic deflection, and the left and right wheels dynamic displacement. The integral absolute error is used as the evaluation criterion. The left and right fuzzy PID controllers' parameters are obtained through particle swarm optimization. Simulation results demonstrate that the particle swarm optimization fuzzy PID active control strategy effectively controls the low-frequency vibration of the TLS suspensions and suppresses the medium- and high-frequency vibration characteristics compared with the traditional skyhook semi-active control strategy. This technology provides a reference for improving the ride comfort of the TLS suspensions. [ABSTRACT FROM AUTHOR]

Inhomogeneous damping distribution leads to the occurrence of complex modes of structures. Complex modes' vibration and acoustic radiation characteristics are different from real modes. This paper studies the complex modal characteristics of inhomogeneously damped plates for forced vibration. We used the state space method to obtain the complex eigenvalues and eigenvectors of the vibration system and calculated the relationship between modal coordinates and frequency under unit force. The results show that the absolute values of the modal coordinates of two conjugate complex eigenvectors are different, and the structure's vibration is dominated by the eigenvectors corresponding to eigenvalues with positive imaginary parts near natural frequencies. When investigating the structural sound radiation in the vibration mode space, each mode's acoustic radiation is not independent but coupled with each other. The influence of the coupling between complex modes on the calculation results of the acoustic radiation power of the plate is studied in this paper. The results show that the coupling effect between modes cannot be ignored when calculating the acoustic radiation power based on complex modes. Finally, the error of calculating acoustic power using the decoupling approximation instead of the complex mode method is analyzed. [ABSTRACT FROM AUTHOR]

Free-play-induced nonlinear dynamic behavior has been one of the most important topics of aeroelastic research in recent decades. In this paper, the describing function (DF) method is developed to investigate the complex dynamic response of a popular all-movable horizontal tail with free-play. Piecewise expressions for the time history and phase portrait of limit cycle oscillation (LCO) are derived by the developed DF method, which is conducive to understand the mechanism of free-play-induced LCO. Another advantage of the developed DF method is the ability to predict the high-order harmonics, which cannot be realized by the classic DF method. A three-dimensional (3D) all-movable horizontal tail model with torsional free-play was designed and manufactured to implement wind tunnel tests via various initial parameters. A good agreement was found between the numerical and experimental results, which can demonstrate the effectiveness of the proposed method. The influence of the initial parameters of the all-movable horizontal tail on the LCO characteristics is analyzed by both numerical calculations and wind tunnel tests. The method and results in this paper can provide a significant reference for the design of all-movable horizontal tail versus the free-play-induced LCO. [ABSTRACT FROM AUTHOR]

Background: The addition of biofeedback and artificial intelligence (AI) in simulation training and serious games has shown promising results in improving the effectiveness of training and can lead to increased engagement, motivation, and retention of information. This systematic literature review explores the integration of biofeedback and artificial intelligence into eXtended reality (XR) training scenarios and is the first review to provide a consolidated overview of applied biofeedback and AI technologies in this area. Method: This review was conducted using keywords related to biofeedback, AI, XR, and training and included papers that: contained the use of biofeedback and AI in XR training scenarios; reported on at least one outcome related to training effectiveness; were published in English; were peer-reviewed; date from 1 January 2016 – 7 February 2022. Results: The results indicate that many studies collect two or more biosignals using a single biosensing device. This is particularly relevant in applied settings, where ease of use and minimal interference in training/education activities is desired. Also, that light, portable devices such as wrist bands, wireless straps, or headbands are preferred. Additionally, eye tracking, electrodermal activity (EDA), and photoplethysmograms (PPG) present as particularly useful biomarkers of stress and/or cognitive load in XR training contexts. A wide variety of machine learning (ML) approaches were used to support biofeedback systems in XR environments. However, a limited number of studies employed real-time analysis of biosignals (just 1% of studies) which indicates current challenges in implementing such systems. Conclusion: The majority of papers meeting the selection criteria were from the fields of education and healthcare. Further research in other domains, such as defense and general industry, is needed to gain a comprehensive understanding of the potential for biofeedback and AI integration in XR training scenarios used in these domains.

Background: Diverticular disease (DD) represents a common gastrointestinal condition that poses a heavy burden on healthcare systems worldwide. A high degree of uncertainty surrounds the therapeutic approaches for the control of symptoms in patients with symptomatic uncomplicated diverticular disease (SUDD) and primary and secondary prevention of diverticulitis and its consequences. Objectives: To review the current knowledge and discuss the unmet needs regarding the management of SUDD and the prevention of acute diverticulitis. Eligibility criteria: Randomized trials, observational studies, and systematic reviews on lifestyle/dietary interventions and medical treatment (rifaximin, mesalazine, and probiotics) of SUDD or prevention of acute diverticulitis. Sources of evidence: The literature search was performed from inception to April 2023, without language restriction, following the modified Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) reporting guidelines. References of the papers selected were checked to identify additional papers of potential interest. The final list of references was evaluated by a panel of experts, who were asked to check for any lack of relevant studies. Charting methods: Information on patient population, study design, intervention, control group, duration of the observation, and outcomes assessed was collected by two authors independently. Results: The review shows a high degree of uncertainty about therapeutic interventions, both dietary/lifestyle and pharmacological, in patients with SUDD, because of the scarcity and weakness of existing evidence. Available studies are generally of low quality, heterogeneous, and outdated, precluding the possibility to draw robust conclusions. Similarly, acute diverticulitis prevention has been seldom investigated, and there is a substantial lack of evidence supporting the role of dietary/lifestyle or pharmacological approaches to reduce the risk of diverticulitis. Conclusion: The lack of robust evidence regarding therapeutic options for gastrointestinal symptoms in SUDD patients and for primary and secondary prevention of acute diverticulitis remains an important unmet need in the management of DD.

This essay is a provocation that seeks to contribute to the (re)naissance of African-centered scholarship through a critical interrogation and engagement of words or concepts that exude criticality yet are frequently used superficially. For Africans (globally), conceived by unfavorable imaginations, critical reflection is vital to enable them to engage in deep, reflective analysis of their thoughts, actions, and experiences. Having been dislocated in many ways, (re)examining assumptions, biases, and beliefs and (re)considering alternative perspectives and ideas must preoccupy African researchers. Through an onto-epistemic prism that centers on both Afrocentric assumptions and decolonial thought, the paper interrogates how the prefix "re" extends beyond simplistic meanings like "again" or "repeat" to offer potentialities for African agency. The paper seeks to contribute toward critical African thought and education as well as supporting the pathways for the African Renaissance. The aim is to explore how the prefix "re" can help to empower Africans to shape their own futures. [ABSTRACT FROM AUTHOR]

Cross-language research involving translation is prevalent in the social sciences yet under-discussed in terms of its ethical impact on participants or the translator her/himself. This paper applies a feminist ethics of 'care' to the topic of translation in cross-cultural, cross-language research. We argue for the importance of emotional intelligence and awareness of emotional labor involved in meaningful, ethical translation between the researcher, translator, and participants. The paper itself is a reflexive conversation between a translator and researcher following six months of data collection involving over 120 interviews and 10 work-life histories. We discuss the opportunities and limitations for more emotionally evolved translation in cross-cultural research, discussing specific strategies for caring about, taking care of, caregiving and care receiving through translation. Applying the 'caring through translation' framework promotes deeper collaboration and relationality between researchers, translators, and participants, grounded in feminist ideals of equitable, ethical knowledge production.

Researchers conducting fieldwork, especially in comparative social research, face the complex issue of conceptualizing and practicing positionality. How we position ourselves affects the research approach, the interpretation of the data and, therefore, the whole research process. This paper discusses my own in-between or 'in-out-sider' positionality during my fieldwork studying the experience of youths in social movements in Thailand and Myanmar in 2020 and 2021. Drawing on data from a visit to Thailand and interviews with 40 Myanmar and Thai youths who participated in the movements, this article documents my experience of the subtle nuances of multiple positionalities and how I navigated through the fieldwork as an in-out-sider researcher. In this comparative context, especially, I believe that my in-out-sider positionality facilitated the research process, from interviewing participants to conducting the field visit. The discussion of this contextually situated positionality challenges the typical explanations of the insider/outsider dichotomy, suggesting the need for a rethinking of certain aspects of this explanation, such as the background and experience of the researcher, and the context in which the researcher and the researched interact. This paper therefore contributes to knowledge around this subject and its application, particularly in the context of comparative social research which studies specific groups of youth activists or protestors.

Most nuclear dyads are characterized by some degree of nuclear and conventional asymmetry. This paper argues that these asymmetries create an environment in which deliberate nuclear first use (DNFU) can be rational. This possibility has been discarded in the formal literature on nuclear escalation because of the common reliance on the assumption of mutually assured destruction (MAD). This paper develops a formal model that traces how and under what circumstances two types of DNFU are rational. First, nuclear imbalances and advancements in counterforce technologies create a damage limitation incentive for a strong actor. Second, conventional asymmetry creates an incentive for the coercive use of nuclear weapons by the weaker player. Moreover, this paper illustrates that these asymmetric conditions are a relevant characteristic in important and very different nuclear dyads: DPRK–US, Pakistan–India, and Russia–US. Thus, the model demonstrates the potential core drivers of DNFU in today's nuclear landscape. [ABSTRACT FROM AUTHOR]

This paper studies the distributed convex optimization of bipartite containment control problem for a class of higher order nonlinear multi-agent systems with uncertain states. For the optimization problem, the penalty function is constructed by summing the local objective function of each agent and combining the penalty term formed by the adjacency matrix. For the unknown nonlinear function and unpredictable states in the system, this paper construct radial basis function Neural-networks and state observer for approaching, respectively. In order to avoid "explosion of complexity," under the framework of Lyapunov function theory, we propose the dynamic surface control (DSC) technology and design the distributed adaptive backstepping neural network controller to ensure all the signals remain semi-global uniformly ultimately bounded in the closed-loop system and all agents can converge to the convex hull containing each boundary trajectory as well as its opposite trajectory different in sign. Simulation results confirm the feasibility of the proposed control method. [ABSTRACT FROM AUTHOR]

Paper board with bending stiffness is usually used as the substrates on cigarette package printing industry. The vibration of these paper boards in high speed affects the printing precision. The dynamic characteristics and stability of moving paper board with finite interior elastic point supports and elastic edges restrained are investigated. First, the energy function of the system is established by using the extended Hamilton’s principle; second, the dimensionless equations of motion for the moving paper board are obtained using the element-free Galerkin method. The equations of motion and the eigenvalue equations of the system are established. The relationship between the first three complex frequencies of the system and the moving speed is then obtained by the numerical calculation. The effects of the elastic point supports, the elastically restrained edges, and the dimensionless speed of the motion on the dynamic stability of the paper board are analyzed. The critical speed when the paper board is in a stable state under different conditions is obtained. The results improve the dynamic stability of the paper board in printing process and provide the theoretical basis for the optimization of printing equipment. [ABSTRACT FROM AUTHOR]

Artificial intelligence (AI) software that analyzes medical images is becoming increasingly prevalent. Unlike earlier generations of AI software, which relied on expert knowledge to identify imaging features, machine learning approaches automatically learn to recognize these features. However, the promise of accurate personalized medicine can only be fulfilled with access to large quantities of medical data from patients. This data could be used for purposes such as predicting disease, diagnosis, treatment optimization, and prognostication. Radiology is positioned to lead development and implementation of AI algorithms and to manage the associated ethical and legal challenges. This white paper from the Canadian Association of Radiologists provides a framework for study of the legal and ethical issues related to AI in medical imaging, related to patient data (privacy, confidentiality, ownership, and sharing); algorithms (levels of autonomy, liability, and jurisprudence); practice (best practices and current legal framework); and finally, opportunities in AI from the perspective of a universal health care system.

Purpose The purpose of the study was to evaluate the reliability, review differences and assess patient satisfaction of electronic patient-reported outcome measures (PROMs) compared with paper PROMs. Methods Participants between 12 and 19 years of age with a knee-related primary complaint were randomized into two groups. Group 1 completed paper PROMs followed by electronic, while Group 2 received the electronic followed by paper. PROMs included the Pediatric International Knee Documentation Committee (Pedi-IKDC), Hospital for Special Surgery (HSS) Pediatric Functional Activity Brief Scale (HSS Pedi-FABS), Tegner Activity Level Scale, Visual Analogue Scale (VAS), PedsQL Teen and a satisfaction survey. Results In all, 87 participants were enrolled with one excluded due to incomplete PROMs. Of the 86 participants, 54 were female and 32 were male with an average age of 14.3 years (12 to 18). A high degree of reliability was found when comparing the paper and electronic versions of the Pedi-IKDC (0.946; p < 0.001), HSS Pedi-FABS (0.923; p < 0.001), PedsQL Teen (0.894; p < 0.001), Tegner Activity Level Scale before injury (0.848; p < 0.001) and the Tegner Activity Level Scale after (0.930; p < 0.001). Differences were noted between the VAS scores, with paper scores being significantly higher than electronic (5.3 versus 4.6; p < 0.001). While not significant, a trend was noted in which electronic PROMs took, overall, less time than paper (10.0 mins versus 11.2 mins; p = 0.096). Of all participants, 69.8% preferred the electronic PROMs, 67.4% felt they were faster, 93.0% stated they would complete forms at home prior to appointments and 91.8% were not concerned about the safety/privacy of electronic forms. Conclusion PROMs captured electronically were reliable when compared with paper. Electronic PROMs may be quicker, will not require manual scoring and are preferred by patients.

Prostate cancer is one of the most common diagnosed cancers in men and the waiting time has become an important issue not only for clinical reasons, but also mostly for the psychological implications on patients. The aim of our study was to review and analyze the literature on waiting times for prostate cancer. In February-March 2019 we performed a search for original peerreviewed papers in the electronic database PubMed (MEDLINE). The key search terms were "prostate cancer AND waiting list", "prostate cancer AND waiting times". We included in our narrative review articles in Italian, English or French, published in 2009-2019 containing original data about the waiting times for prostate cancer. The literature search yielded 680 publications. Finally, we identified 8 manuscripts eligible for the review. The articles were published between 2010 and 2019; the studies involved a minimum of 16 to a maximum of 95438 participants. Studies have been conducted in 6 countries. The waiting times from cancer suspicion to histopathological diagnosis and to treatment had an important reduction in the last years, and this constant decrease could lead to an increase of patients' satisfaction.

In nonclinical safety studies for new drug development, healthy animals have been commonly used. However, in some cases, the use of animal models of human disease is considered to be more favorable in evaluating risks in patients. To elucidate the current status of the use of animal models for nonclinical safety assessment, an internal questionnaire from the Japan Pharmaceutical Manufacturers Association and surveys (questionnaire period: August 27 to September 30, 2015) of both common technical documents and review reports of approved drugs (approval period: May 1999 to May 2017) disclosed by the Pharmaceutical and Medical Devices Agency were conducted. Although there were some concerns and limitations raised, the survey results revealed that animal models have been used in nonclinical safety assessment on a case-by-case basis and that nonclinical safety studies using animal models were included in the data packages of several approved drugs in Japan. The survey results also revealed that nonclinical safety studies using animal models have become more frequent in the past few years. In almost all cases, useful information, such as signs of toxicity under disease conditions and mechanisms of toxic change, was obtained from the results of nonclinical studies using animal models.

There are a growing number of older adults with age-related vision loss (ARVL) for whom technology holds promise in supporting their engagement in daily activities. Despite the growing presence of technologies intended to support older adults with ARVL, there remains high rates of abandonment. This phenomenon of technology abandonment may be partly explained by the concept of self-image, meaning that older adults with ARVL avoid the use of particular technologies due to an underlying fear that use of such technologies may mark them as objects of pity, ridicule, and/or stigmatization. In response to this, the proposed study aims to understand how the decision-making processes of older adults with ARVL, as it relates to technology adoption, are influenced by the negotiation of identity. The study protocol will justify the need for this critical ethnographic study; unpack the theoretical underpinnings of this work; detail the sampling/recruitment strategy; and describe the methods which included a home tour, go-along, and semistructured in-depth interview, as well as the collective approach taken to analyze the data. The protocol concludes by examining the ethical tensions associated with this study, including a focus on the methods adopted as well as the ethical challenges inherent when working with an older adult population experiencing vision loss.

Nephrotoxicity is one of the more common causes of attrition in nonclinical drug development. Like most tissues, the kidney has a limited number of ways of responding to toxicological insults from diverse mechanistic pathways, which can limit the ability to determine mechanisms of renal injury using the assays routinely performed in preclinical toxicologic studies. In situations where the renal injury is unusual in morphology or if a therapeutic margin is low, additional investigative techniques may be needed to identify a potential mechanism of toxicity in order to inform clinical risk assessment or establish human relevance and translatability of the toxicity. While routine microscopic evaluation can suggest a specific pathogenesis, understanding the mechanism of renal injury often requires additional hypothesis-driven investigations and specialized techniques to obtain the data necessary to identify a nephrotoxic mechanism. Nonclinical mechanistic investigations can be resource-intensive and often yield limited new information. Although there are multiple avenues to investigate renal toxicity, no single mechanistic study or prescriptive battery of tests will identify the pathophysiologic basis for every potential mechanism of renal injury. To aid the nonclinical investigator, we outline a tiered approach for prioritizing investigations to provide a rational and linear road map for the exploration of mechanisms of drug-induced kidney injury.

Abstract Artificial intelligence (AI) is rapidly moving from an experimental phase to an implementation phase in many fields, including medicine. The combination of improved availability of large datasets, increasing computing power, and advances in learning algorithms has created major performance breakthroughs in the development of AI applications. In the last 5 years, AI techniques known as deep learning have delivered rapidly improving performance in image recognition, caption generation, and speech recognition. Radiology, in particular, is a prime candidate for early adoption of these techniques. It is anticipated that the implementation of AI in radiology over the next decade will significantly improve the quality, value, and depth of radiology's contribution to patient care and population health, and will revolutionize radiologists' workflows. The Canadian Association of Radiologists (CAR) is the national voice of radiology committed to promoting the highest standards in patient-centered imaging, lifelong learning, and research. The CAR has created an AI working group with the mandate to discuss and deliberate on practice, policy, and patient care issues related to the introduction and implementation of AI in imaging. This white paper provides recommendations for the CAR derived from deliberations between members of the AI working group. This white paper on AI in radiology will inform CAR members and policymakers on key terminology, educational needs of members, research and development, partnerships, potential clinical applications, implementation, structure and governance, role of radiologists, and potential impact of AI on radiology in Canada.

This study presents experimental analysis and numerical modeling of hygroscopic moisture buffering by paper and books. First, a literature review of moisture transport properties of paper is presented. Experimental work on two paper types includes SEM analysis of the paper structure, determination of sorption isotherms and water vapor permeability measurements. A hysteretic model for paper is presented, which is based on the measurement of the main adsorption and desorption curves. It is shown that the water vapor permeability in a hysteretic model is dependent on the moisture content and not on the relative humidity. Books consist of several paper sheets with air layers between the sheets. To take the air layers into account, a parallel transport model is proposed to determine the effective moisture transport properties of books taking into account the air layers. The dynamic hygroscopic behavior of small book samples was measured. It is shown that, although the water vapor permeability of different paper types can be quite different, the effusivity of a book highly depends on the presence of the air layers and can therefore remain comparable for different paper types.

Objectives The purpose of this article is to determine how many of the current peer-reviewed studies of ankle foot orthoses (AFOs) on children with cerebral palsy (CP) have included adequate details of the design and material of the AFO, to enable the study to be reproduced and outcomes clearly understood. Methods A thorough search of studies published in English was conducted in March 2015, with no restriction on dates, within all major databases using relevant phrases. These searches were then supplemented by tracking all key references from the appropriate articles identified. Study selection The inclusion criteria were as follows: (1) population - children with CP; (2) intervention - AFOs; and (3) outcome measure. One reviewer extracted data regarding the characteristics of the included studies, with the extracted data checked for accuracy and completeness by a second reviewer. None of the studies reviewed gave adequate details of the AFOs. Only 3.6% (n = 2) of papers tested the stiffness. Many studies (54.5%) did not describe the material used nor the material thickness (72.7%). None of them gave any clinical justification for the chosen design of AFO. Conclusions There is a clear paucity of detail regarding the design and material used in AFOs on studies involving children with CP. Such a lack of detail has the potential to affect the validity of the reported outcomes, the ability to reproduce the studies and may misinform clinical practice. [ABSTRACT FROM AUTHOR]

This study examined whether the contribution of social capital to household economic outputs was greater than that of other types of capital, whether different dimensions of social capital contribute equally to household income, and whether the role of social capital varies among different categories of house- holds. We developed a reduced-form model of the household production function, in which social capital is treated as a production factor similar to other conventional factors such as physical capital, labor, and human capital, with household income and expenditure as dependent variables. The results show that social capital has a strong and positive contribution to household income, and the positive contribution of social capital to the general (the poor) house- hold's income is greater than that of the paper-recycling (the rich) household's income. In contrast to other studies, the number of memberships in associations does not have an impact on household income. [ABSTRACT FROM AUTHOR]
