Access, Computational Analysis, and Fair Use in the Digitized Nineteenth- Century Press

This essay looks to the near history of copyright, commercially licensed resources, and fair use that shapes digital scholarship on nineteenth-century periodicals today. Using the digitization of British Library newspapers as a case study, I demonstrate how arguments about access to public domain materials do not fully account for the complex international landscape of rights and exceptions for digital periodicals resources. This landscape is also changing with the emergence of legal exceptions for computational research methods like text and data mining. These methods may point to new forms of scholarly communication, particularly "transformative uses" that work around the restrictive vestiges of copyright law. Ultimately, this essay claims that scholars need to understand the changing parameters of copyright, not simply as a set of rules that affects their day-to-day work but as an opportunity to shape the law and advocate for creative forms of research and scholarly communication

Mr. Penumbra’s 24-Hour Listserv

Presented at the MVSA Lifetime Achievement Award Roundtable in Honor of Patrick Leary. This paper claims that the VICTORIA-L email listserv, which Leary inaugurated in 1993, represents one of the longest running digital humanities projects in Victorian studies. Instead of technical sophistication, VICTORIA-L underscores the crucial role of infrastructure and care labor in digital scholarly resources and networks

Biophysical investigations of photosynthetic reaction centres from Rhodobacter sphaeroides

Site-directed mutagenesis was used to produce a series of mutant reaction centres from the purple bacterium Rb. sphaeroides. These mutants were investigated using a combination of functional assays and X- ray crystallography in order to correlate structure/function relationships. In particular the effect of the protein environment on the carotenoid pigment in the reaction complex has been investigated. The carotenoid is held within a largely hydrophobic pocket within the reaction centre complex, assuming a twisted 15,15' cis conformation. A small number of polar amino acid residues are positioned towards one end, forming almost a ring around the pigment molecule. Each of these amino acids was replaced with a non-polar residue of an approximately similar size: Trp M115-Phe, Ser M119-Ala, Met M122-Leu, Trp M157-Phe and Tyr M177-Phe. The mutant reaction centres were expressed in a background lacking light-harvesting complexes, permitting observation of the spectral characteristics of the complex in the bacterial cell and chromatophores. A range of techniques were then applied to attempt to identify the effects of the mutations on the reaction centre carotenoid. One additional mutant complex was investigated, in which an amino acid in close proximity to the BChl special pair was mutated (Phe to Arg M197). Limited investigation of this mutant complex had already identified altered spectral characteristics, although the precise mechanism by which this spectral shift was produced by the mutation was unclear. The investigations performed fell into three groups. The initial focus was concentrated on establishing whether the mutant reaction centre complexes were still being properly assembled by the bacteria. To this end, the ability of the bacteria to insert complexes into the membrane, the stability of the complexes upon removal from the membrane, and the ratio of pigments bound within the complex were determined. The second group of investigations utilised specialised spectroscopic techniques. Circular dichroism studies showed that the carotenoid was apparently binding in a similar fashion in the mutant and wild-type complexes, and that the blue-shifted P band in the absorption spectra of RM197 strains was also manifested in the CD spectra. ESR was the final spectroscopic technique utilised. It was used to investigate the ability of the various RC complexes to transfer the triplet energy from BChl to carotenoid. All the carotenoid binding site mutants returned wild-type signals. However, those carrying the RM197 mutation showed marked differences from the wild-type. The mutation at RM197 affected the values of the ESR field splitting parameters, and allowed the triplet energy to be transferred at temperatures much lower than that determined for the wild-type.

"Digital Pedagogy Unplugged"

Curatorial note from Digital Pedagogy in the Humanities: Paul Fyfe provocatively asks, “Can there be a digital pedagogy without computers?” and offers several examples of assignments that treat “the ‘digital’ in the non-electronic senses of that word: something to get your hands on, to deal with in dynamic units, to manipulate creatively.” Rethinking digital pedagogy in this way not only allows students and instructors with varied access to electronic technologies to explore new kinds of assignments but also creates useful linkages between thinking about the materiality of print artifacts and that of digital texts. For example, Fyfe imagines a curatorial assignment where students gather, remix, and analyze physical artifacts rather than images on a screen. Such assignments could be scaffolded with digital assignments that use computational tools to emphasize shared methodological and theoretical principles

Coronary sinus sampling of cytokines after heart transplantation: Evidence for macrophage activation and interleukin-4 production within the graft

AbstractObjectives. This study was undertaken to evaluate the organ-specific release of cytokines after heart transplantation and to assess any correlation with transplant rejection. This cytokine profile should document the relative activation of mononuclear cell subsets within the graft.Background. Up to 60% of mononuclear cell infiltrating the cardiac allograft during rejection are macrophages, but their rote is undetermined. The T lymphocytes are activated, but the activity of specific T cell subsets is not known. We sought to assess for the first time in humans the in vivo activation of mononuclear cell subsets by measuring coronary sinus cytokine levels after heart transplantation.Methods. Palred superior vena cava and coronary sinus serum samples were assayed for interkeukin (IL)-2, IL-4 and IL-6, soluble IL-2 receptors, tumor necrosis factor-alpha and neopterin in 10 patients at the time of 40 routine endomyocardial biopsy procedures. All cytokine measurements were made by using enzyme-linked immunosorbent assay; neopterin was measured by using radioimmunoassy.Results. Interleukin-2 levels were not detectable (<0.8 U/ml) in either the superior vena cava or the coronary sinus in the presence or absence of rejection. Interleukin-2 receptor levels were uniformly elevated to 1,283 U/ml in the superior vena cava and to 1,232 U/ml in the coronary sinus, with no correlation with rejection severity. Interleukin-4 levels were consistently higher in coronary sinus serum than in peripheral blood (229 vs. 61 pg/ml, p < O.0005), but there was no relation with rejection. Interleukin-6 levels were higher in the coronary sinus than in me superior vena cava (200 vs. 120 pg/mi, p < 0.05). Tumor necrosis factor-alpha showed consistently elevated levels in coronary sinus serum (68 vs. 17 pg/ml, p < 0.0005), with no relation with rejection. Neopterin, which is produced only by activated macro-phages, was also consistently elevated in the coronary sinus (2.5 vs. 2.2 nmol, p = 0.08).Conclusions. The cardiac allograft is a major source of cyto-kines after heart transplantation. The cytokine profile allows the activity of subsets of the mononuclear cell infiltrate to be investigated. Elevated coronary sinus activity of the macrophage specific metabolite neopterin suggests macrophage activation within the allograft. This possibility is supported by elevated coronary sinus levels of tumor necrosis factor-alpha and IL-6. The T lymphocytes are activated, as evidenced by high soluble IL-2 receptor levels, but IL-2 production was suppressed by conventional immunosup-pressive therapy. Coronary sinus IL-4 levels represent T helper-2 cell activation within the graft despite immunosuppression. We could find no temporal relation between the coronary sinus or superior vena cava cytokine concentration or profile and severity of rejection on concurrent biopsy studies

Feasibility and acceptability of a remotely delivered, home-based, pragmatic resistance ‘exercise snacking’ intervention in community-dwelling older adults: A pilot randomised controlled trial

Background: Very few older adults meet current muscle strengthening exercise guidelines, and several barriers exist to supervised, community-based resistance exercise programs. Older adults therefore require access to feasible resistance exercise modalities that may be performed remotely. This pilot study assessed the feasibility and acceptability of undertaking a four-week home-based resistance ‘exercise snacking’ intervention (performed either once, twice, or thrice daily) when delivered and monitored remotely in older adults. Methods: Thirty-eight community-dwelling older adults [mean ± SD age 69.8 ± 3.8 y, 63% female] were randomised to complete resistance ‘exercise snacks’ (9-minute sessions) either once (n = 9), twice (n = 10), or thrice (n = 9) daily, or allocated to usual-activity control (n = 10). Exercise adherence and adverse events were assessed using an exercise diary, and acceptability of the intervention was explored using an online questionnaire. Physical function [balance, 5-times sit-to-stand (STS), and 30-second STS tests] was assessed remotely at baseline and follow-up using videoconferencing. Results: The intervention was feasible and safe, with 100% participant retention, high adherence (97, 82, and 81% for once, twice, and thrice daily, respectively), and only two adverse events from a total of 1317 ‘exercise snacking’ sessions. The exercise intervention was rated as enjoyable (75% reported their enjoyment as ≥ 4 on a 5-point Likert scale), easy to perform, and most (82%) planned to continue similar exercise at home. We also found it was feasible to assess measures of physical function via videoconferencing, although effect sizes for 4-week changes in both 5-STS (d range, 0.4–1.4) and 30-STS (d range, 0.7–0.9) following the exercise intervention were similar to controls (d = 1.1 and 1.0 for 5-STS and 30-STS, respectively). Conclusions: Resistance ‘exercise snacking’ may be a feasible strategy for engaging older adults in home-based resistance exercise when delivered and monitored remotely. The findings of this pilot feasibility trial support the need for longer-term studies in larger cohorts to determine the effectiveness of resistance ‘exercise snacking’ approaches for improving physical function in older adults. Trial registration: The trial was retrospectively registered on 10/11/2021 with the Australian New Zealand Clinical Trials Registry (ANZCTR) (ACTRN12621001538831)
