Assessing plasticity in the primary sensory cortex and its relation with atypical tactile reactivity in autism: A TMS-EEG protocol.

Atypical sensory reactivity is a cardinal presentation in autism. Within the tactile domain, atypical tactile reactivity (TR) is common, it emerges early, persists into adulthood, and impedes social interaction and daily functioning. Hence, atypical TR is a key target for biological intervention to improve outcomes. Brain mechanisms informing biological interventions for atypical TR remains elusive. We previously reported hyper-plasticity in the motor cortex in autistic adults and found that repetitive transcranial magnetic stimulation (rTMS), designed to strengthen inhibitory processes in the brain, reduced hyper-plasticity. Whether the primary sensory cortex (S1) is characterized by hyper-plasticity, which may underlie atypical TR in autism is unknown. We aim to test whether hyper-plasticity in the S1 underlies atypical TR in autism, and investigate if a single session of rTMS can safely reduce hyper-plasticity in S1 in autistic adults. Plasticity will be assessed in the left S1 with integrated paired associative stimulation and electroencephalography (PAS-EEG) paradigm in 32 autistic adults and 32 age-, sex-, and intelligence quotient-matched controls. Autistic participants will be further randomized (double-blind, 1:1) to receive a single-session of either sham or active 20 Hz bilateral rTMS over the S1 and the plasticity will be re-assessed over the left S1 on the same day. Atypical TR has been identified as one of the top clinical research priorities that can influence outcome in autistic population. The study findings can be highly valuable to further elucidate the mechanism underlying atypical TR, which in turn can help with developing a mechanism-driven intervention.

Research on Religion and Aging among Black Americans and Mexican Americans: The Impact of the National Institute on Aging.

For 50 years, the National Institute on Aging (NIA) has supported and promoted research on religious involvement among older adult populations. This article discusses the ways that NIA funding has 1) broadened our understanding of how religious involvement is conceptualized and measured; 2) explored the important role of social networks and interactions within religious communities in relation to congregants' health; 3) supported research on national samples of the U.S. population to explore demographic variability in religious practices and beliefs, as well as their social correlates; and 4) examined health-relevant frameworks and topics in relation to religion's association with physical and mental health and well-being. The article focuses on research on African Americans and Mexican Americans as well as work that compares these populations to non-Latino Whites and Black Caribbeans. In this article, we provide an overview of selected research topics in the area of religion and aging, including Conceptualization and Measurement of Religious Participation; Religion and Mental Health; Religion and Physical Health; Church-Based Informal Support; Church Support and Mental and Physical Health; Religious Coping, and the Use of Clergy for Serious Problems. Scholarship and research supported by the NIA have fundamentally contributed to a deepening understanding of why and how religion matters for the health and social well-being of African American, Black Caribbean, and Mexican American older adults.

Target sensitivity study of density transition-injected electrons in laser wakefield accelerators

While plasma-based accelerators have the potential to positively impact a broad range of research topics, a route to application will only be possible through improved understanding of their stability. We present experimental results of a laser wakefield accelerator in the nonlinear regime in a helium gas jet target with a density transition produced by a razor blade in the flow. Modifications to the target setup are correlated with variations in the plasma density profile diagnosed via interferometry and the shot-to-shot variations of the density profile for nominally equal conditions are characterized. Through an in-depth sensitivity study using particle-in-cell simulations, the effects of changes in the plasma density profile on the accelerated electron beams are investigated. The results suggest that blade motion is more detrimental to stability than gas pressure fluctuations, and that early focusing of the laser may reduce the deleterious effects of such density fluctuations.

A Bibliometric Analysis of Convection-Permitting Model Research

Convection-permitting models (CPMs) are receiving growing scientific interest for their capability to accurately simulate extreme weather events at a kilometer-scale spatial resolution, offering valuable information for local climate change adaptation. This study employs both qualitative and quantitative bibliometric analysis techniques to examine research trends in CPM, utilizing data from 3,508 articles published between 2000 and 2023. The annual number of publications exhibits a linear increase, rising from fewer than 50 in 2000 to over 250 after 2020, with the majority of research originating from the US, China, the UK, and Germany. The most productive institutes include the National Oceanic Atmospheric Administration (NOAA) and the National Center for Atmospheric Research (NCAR) in the US, each contributing over 10% of total publications. Title and abstract terms in publications related to keywords such as ”scenario”, ”climate simulation”, etc., dominate publications from 2018 to 2023, coinciding with advances in computing power. Notably, terms associated with CPM physical processes received the highest citations from 2000 to 2023, underscoring the importance of such these research topics. Given the computational expense of running CPMs and the increasing demand for future predictions using CPMs, novel methods for generating long-term simulations are imperative.

When cities broke into the global stage: 20 years since the publication of ‘Cities and Climate Change’

This short symposium revisits the book Cities and Climate Change by Harriet Bulkeley and Michelle Betsill and its role in establishing cities as central actors in climate change governance. The contributors to this symposium reflect on the research themes and the book’s legacy from their disciplinary perspectives. The first response explores the tensions between the elevation of cities as sites for climate action and the persistent lack of state action, arguing for meaningful public participation and a labour of making visible how city-based practices respond to climate change. The second response examines how the book has enabled generations of scholars to appreciate the complex constitution of city actors and how they interact/enact global climate governance yet remain frustratingly marginal in the discipline of International Relations. The third response explores how the book positioned the urban as a problem space, a manageable scale of intervention, and a political space with the capacity to enact innovation, triggering new questions about the potential and limits of the expanding responsibilities of cities. The fourth response argues that as cities become active in adaptation, they need to engage in an anticolonial politics of love and hospitality that sheds ‘security’ and makes the self vulnerable to ‘others’ for an effective response to climate change. The symposium concludes with a recap by Betsill and Bulkeley which underscores the variety of interdisciplinary debates that the book has generated, and its influence on current thinking on debates on climate change governance.

Relationship between periodontitis and chronic obstructive pulmonary disease: a bibliometric analysis from 1945 to 2023.

Chronic obstructive pulmonary disease (COPD) and periodontitis are common chronic diseases. The presence of either of the two diseases increases the risk of the other, whereas managing one reduces the risk of the other. This study aimed to summarize the current state of research and trends in this field using bibliometric analysis and visualization. We used PubMed to search and download all periodontal disease- and COPD-related studies published until August 20, 2023. We further performed bibliometric analysis on the text R and Python software and visualized the results using Gephi and VOSviewer to construct latent Dirichlet allocation models that summarize idiosyncratic research themes. A total of 2, 109 publications were analyzed, with recent ones focusing on risk factors and pandemics. The country that produced the most publications was the United States with 427 publications. The most cited article was by Prof. Wang Zuomin. International Journal of Chronic Obstructive Pulmonary Disease ranked first in publications. Keywords were focused on Risk Factors and Pandemics. In addition, COVID- 19, SARS-CoV-2 and coronavirus infections have become a research hotspot since 2020. However, little attention has been paid to environmental contamination and biological mechanisms. Research on periodontitis and COPD is expanding, and it currently focused on exploring risk factors and conducting clinical epidemiological studies. This exhaustive study provides a comprehensive summary of trends in this field and has important clinical implications for the screening and treatment of patients with COPD and periodontitis.

Knowledge leakage and collaborative innovation: a systematic literature review

ABSTRACT Knowledge leakages often pose strategic challenges when companies engage in collaborative innovation activities. This study comprehensively explores the complex relationship between knowledge leakage and innovation collaboration. This research uses a systematic literature review by selecting 82 articles from the Scopus database. Content analysis identifies critical issues and research gaps mapped into cluster themes. VOSviewer is used to visually represent these research cluster themes. This study finds that the number of articles on this topic emerged in 2000 and has fluctuated since, showing an increasing trend of research published in reputable journals by well-known publishers. Knowledge leakage is classified into three categories: a transfer process or mechanism, a loss or risk, and an unintentional action. In addition, the findings reveal seven research themes addressing this topic. The research proposes an IPO (Input-Process-Output) framework for future research directions. This study offers a new perspective that enriches the topic and provides valuable insights for academics and practitioners.

PATHS TO RESEARCH: A LITERATURE REVIEW ON HIGH SCHOOL REFORM, LAW 13.415/2017

This article presents data and reflections on the reform of secondary education, based on a systematic literature review carried out between September 2021 and January 2022. The objective was to look for possible gaps left by the selected scientific articles, in order to understand which research paths are possible in view of the reform of secondary education. This is a qualitative, documentary investigation, based on journals from the CAPES Qualis System database (four-year period 2013–2016, the latest evaluation available at the time of this investigation), in the area of ​​education assessment. A1 journals whose databases were in Federal and State Universities were analyzed, from 2017 to 2021, using the descriptors “secondary education reform” and “new secondary education”. We have observed a large number of studies related to Law 13,415/2017, which demonstrate a multitude of research paths and themes, covering Brazil from North to South. These studies highlight the researchers' concern with cultural diversity, diverse youth, the scarcity and precariousness of public schools, and the neglect and devaluation of the teaching profession, serving as a theoretical basis for many other ongoing studies.

Science at the Secretariat of the International Seabed Authority: post-normal science for recalibration of policy instruments.

Post-normal conditions require post-normal resolutions. When stakes are high and values are disputed, policy discussions and decisions cannot rely on science alone. Such discussions require post-normal science, which centralizes the qualitative value of diverse knowledge groups. We discuss the usefulness of post-normal science in the context of the work of the Secretariat at the International Seabed Authority. In particular, we explore the need to expand the understanding of science and knowledge – the key components informing deep-seabed policies. Marine science encompasses a broad range of research topics and interests – from blue humanities with analyses of human-Ocean relations, to physics of particulate matter, to marine policy research. The increasing number of disciplines applied to marine science demonstrates growth in our collective knowledge of the Ocean and, in turn, increased realization and appreciation of the limitations of what we know. Such knowledge challenges are discussed among natural and social scientists. The Secretariat depends on broad expertise, from natural sciences, social sciences, civil society and beyond. In short, we argue that post-normal science can help metaphorically recalibrate policy-shaping instruments (the practice) so that decision-making processes and policy agendas are implemented for transformative actions.

Sometimes momentarily, sometimes for years

The poem sometimes momentarily, sometimes for years, is part of a group of poems I have been working on, experimenting with a process of erasure and restructuring of my own texts (book chapters, essays and conference talks). In a moment when my creative writing practice was feeling uncomfortably fallow, Emma Filtness’ presentation of her erasure work Bandaged Dreams[i], at the Visceral Bodies symposium, April 2023, seemed to suggest a possible way back in. I began to experiment with erasure - though, somewhat unconventionally for erasure poetry, I am both the author of the ‘found’ text and the erasure. In putting my academic texts through this process, my aim was to give back to the themes of my research the fluidity, ambivalence and uncertainty rightfully theirs, before I tamed them into an academic structure. The original text remains valid, in its own form, but I could sense something else beneath the text, something related to why I write at all. I write because language terrifies me, because language is slippery, always too much and too little. And because, as poet Jennifer S. Cheng suggests, ‘Sometimes it is a broken narrative, a half-language, that brings us to tears.’[ii] I see this poetry project as a chance to lean into the fragmented, searching element of my writing practice, to which I am sometimes nervous to give free rein, for fear of becoming incomprehensible when what I want to talk about is already difficult to articulate. It is also a way to explore my relationship to ‘academic’ writing, as a first-generation academic. I draw on Jack Halberstam’s questioning of the kinds of knowledge and learning produced by ‘disciplinary correctness’[iii] and the potential for ‘alternative ways of knowing and being’[iv], particularly those explored through Halberstam’s conceptualisation of failure. More broadly, my poetic-prose and poetry writing practice aims to perform the often ambivalent and contradictory experience of early motherhood. This practice touches upon the embodied nature of care, the effects of motherhood on language, and writing as an act of survival. Alongside my creative life writing practice, my ongoing PhD research project looks at how, through theories of the spectral, intersectionality, queerness, feminism, disability, failure and anecdote, we might aspire to transform and re-possess language, in an attempt to express those experiences most difficult to put into words. Both my creative and critical practice specifically explore a recurring connection between my experience of motherhood and ideas of haunting, of presence and absence and repetition (daily and generational).

What is the evidence for the impact of ocean warming on subtropical and temperate corals and coral reefs? A systematic map

BackgroundSubtropical coral reefs are comparatively understudied compared to tropical coral reef ecosystems, yet also host a diverse and abundant array of marine life and provide substantial socio-economic benefits to communities. Research into the impacts of ocean warming on subtropical coral reefs has increased over the past two decades due to increase frequency and intensity of bleaching and degradation of these ecosystems. Understanding the extent of research effort and type of evidence assessing the response of subtropical corals and reefs to ocean warming provides valuable insight into global patterns in research efforts allowing critical knowledge gaps to be identified. A comprehensive understanding the impact of ocean warming on these systems will underpin our ability to predict and respond to future changes on subtropical coral reefs. Here, a systematic-map approach is used to identify recent research effort, from 2010 to 2023, and highlight patterns in the type, scale, and location of research conducted and as well as identify the availability of data and evidence reported.MethodsPrimary literature was identified by searching Scopus and Science Citation Index Expanded through Web of Science Core Collection databases. The methodologies provided in a previously published systematic map protocol were applied, and 90 primary research publications were subsequently identified. Data extraction from the identified literature included bibliometric data, discipline and type of research, type of data reported and how it was recorded, and data availability.FindingsThe identified literature consisted primarily of experimental (49%) and observational (39%) studies. The majority of the primary literature investigated corals in the ecoregions of Southern China (13%), Western Mediterranean (10%) and across a total of seven ecoregions grouped within Oceania (29%). Stressors reported in the literature as drivers of ocean warming reflect the standardisation of methods applied in reporting of events within the literature. Standardised metrics related to degree heating weeks (DHW) and marine heatwaves (MHW) have been reported when assessing the occurrence and severity of drivers, and are increasing in recent years, particularly in Australia. Finally, the need for increased research effort across much of the subtropics is evident, particularly for understudied regions such as the Western Indian Ocean where there are far fewer studies than other similar subtropical coral reef ecosystems.ConclusionsClimatic change, increasing ocean temperatures, and the impacts to subtropical and temperate coral reefs are of increasing concern to policy makers and researchers alike. This systematic map provides a broad overview of research topics and effort around the globe since 2010 and identifies areas where more research effort is urgently needed. Our study has identified major research clusters in Asia, Australia, the Mediterranean, and North America and gaps of research in regions such as the East Indian Oceans. Of the research conducted to date approximately one third reports on evidence related to marine protected areas and the vast majority of evidence is from close/territorial sea locations, providing important knowledge base for management of these areas. Of the 17 studies reporting on specific extreme events (rather than experimental studies which is the majority of evidence identified here) 13 have been published since 2019, with the majority reporting on events occurring in 2019/20 indicating a trend of increasing evidence in recent years (a total of 7 studies from 2010 to 2013, compared to over 10 studies published annually since 2019 up to mid-2023).
