This essay argues that important development and natural resource management initiatives that seek to expand meaningful participation by rural communities directly affected by such ventures can be usefully examined as democratic technologies. Drawing upon nearly two decades of experience designing, implementing, and researching forest co-management programs in India, the essay examines the analogous practices through which democracy and forest management science become contested regulatory ideals while creating the deliberative spaces in which post-Habermasian public spheres can be constructed. The analysis of (...) disciplinary tendencies, bureaucratic transition, and emerging solidarities among historically marginalised groups responding to the performance of democracy and scientific forest management is used to offer revisions to the more sweeping critiques of technology as fundamentally anti-democratic.

Transcription is a fundamental cellular process and the first step in gene regulation. Although RNA polymerase (RNAP) is highly processive, in growing cells the progression of transcription can be hindered by obstacles on the DNA template, such as damaged DNA. The authors recent findings highlight a trade‐off between transcription fidelity and DNA break repair. While a lot of work has focused on the interaction between transcription and nucleotide excision repair, less is known about how transcription influences the repair of DNA (...) breaks. The authors suggest that when the cell experiences stress from DNA breaks, the control of RNAP processivity affects the balance between preserving transcription integrity and DNA repair. Here, how the conflict between transcription and DNA double‐strand break (DSB) repair threatens the integrity of both RNA and DNA are discussed. In reviewing this field, the authors speculate on cellular paradigms where this equilibrium is well sustained, and instances where the maintenance of transcription fidelity is favored over genome stability.

Writing about the history and politics of epidemics and pandemics requires stepping into a historiography that is expansive, transnational, and slotted into specific historical periods. This essay considers the main debates in this expansive historiography and highlights the strengths and limitations of dominant historiographical approaches to the study of epidemics and pandemics. This essay also interrogates the framing of three thematic periods, or categories, commonly identified by historians and social scientists in analyses of epidemics and pandemics: categories of “colonial health,” (...) “international health,” and “global health.” As this essay underscores, scholarship often analyzes epidemics and pandemics through overlapping and complex historical temporalities involving colonization, decolonization, and globalization. However, this approach is often constrained by the limitations of existing archives and the overwhelming focus of published scholarship on dominant institutions, scientific and political figures, and specific disease outbreaks that are commonly associated with categories of “colonial health,” “international health,” and “global health” from the late nineteenth to the present. As a result, scholarship may include linear narratives that flatten or generalize the legacies of epidemics and pandemics. The links between pathogens and pathologies are not linear, however, and colonial structures of power, disease tropes, and surveillance doctrines often persist across time and space. This essay ultimately seeks to challenge and complicate these dominant framings and categories from within. This approach highlights the connectedness—and complex continuities and discontinuities—in the political, economic, social, and scientific perceptions of and approaches to epidemic and pandemic risks.

BackgroundInstitutional review boards (IRBs) have been criticised for delays in approvals for research proposals due to inadequate or inexperienced IRB staff. Artificial intelligence (AI), particularly large language models (LLMs), has significant potential to assist IRB members in a prompt and efficient reviewing process.MethodsFour LLMs were evaluated on whether they could identify potential ethical issues in seven validated case studies. The LLMs were prompted with queries related to the proposed eligibility criteria of the study participants, vulnerability issues, information to be disclosed (...) in the informed consent document (ICD), risk–benefit assessment and justification of the use of a placebo. Another query was issued to the LLMs to generate ICDs for these case scenarios.ResultsAll four LLMs were able to provide answers to the queries related to all seven cases. In general, the responses were homogeneous with respect to most elements. LLMs performed suboptimally in identifying the suitability of the placebo arm, risk mitigation strategies and potential risks to study participants in certain case studies with a single prompt. However, multiple prompts led to better outputs in all of these domains. Each of the LLMs included all of the fundamental elements of the ICD for all case scenarios. Use of jargon, understatement of benefits and failure to state potential risks were the key observations in the AI-generated ICD.ConclusionIt is likely that LLMs can enhance the identification of potential ethical issues in clinical research, and they can be used as an adjunct tool to prescreen research proposals and enhance the efficiency of an IRB.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)
