Beyond the Back Room: The Role of Metadata and Catalog Librarians in Digital Humanities

Many professors and students are surprised to learn about the variety of skills metadata and catalog librarians possess that can benefit their digital humanities projects. Metadata and catalog librarians already have experience in areas such as developing project metadata schemas and controlled vocabularies, as well as providing suggestions for project organization, and have the basic abilities needed to support learning new skills such as XML and TEI. This chapter will offer perspectives on how a metadata and catalog librarian can contribute to digital humanities projects. A case study focusing on the involvement of the Metadata and Catalog Librarian with the Digital Humanities Initiative (DHi) at Hamilton College will be used to illustrate one example of how to become successfully involved in digital humanities research on campus

Two intracellular and cell type-specific bacterial symbionts in the placozoan Trichoplax H2

Placozoa is an enigmatic phylum of simple, microscopic, marine metazoans(1,2). Although intracellular bacteria have been found in all members of this phylum, almost nothing is known about their identity, location and interactions with their host(3-6). We used metagenomic and metatranscriptomic sequencing of single host individuals, plus metaproteomic and imaging analyses, to show that the placozoan Trichoplax sp. H2 lives in symbiosis with two intracellular bacteria. One symbiont forms an undescribed genus in the Midichloriaceae (Rickettsiales)(7,8) and has a genomic repertoire similar to that of rickettsial parasites(9,10), but does not seem to express key genes for energy parasitism. Correlative image analyses and three-dimensional electron tomography revealed that this symbiont resides in the rough endoplasmic reticulum of its host's internal fibre cells. The second symbiont belongs to the Margulisbacteria, a phylum without cultured representatives and not known to form intracellular associations(11-13). This symbiont lives in the ventral epithelial cells of Trichoplax, probably metabolizes algal lipids digested by its host and has the capacity to supplement the placozoan's nutrition. Our study shows that one of the simplest animals has evolved highly specific and intimate associations with symbiotic, intracellular bacteria and highlights that symbioses can provide access to otherwise elusive microbial dark matter

The XMM-Newton EPIC X-ray Light Curve Analysis of WR 6

We obtained four pointings of over 100 ks each of the well-studied Wolf-Rayet star WR 6 with the XMM-Newton satellite. With a first paper emphasizing the results of spectral analysis, this follow-up highlights the X-ray variability clearly detected in all four pointings. However, phased light curves fail to confirm obvious cyclic behavior on the well-established 3.766 d period widely found at longer wavelengths. The data are of such quality that we were able to conduct a search for "event clustering" in the arrival times of X-ray photons. However, we fail to detect any such clustering. One possibility is that X-rays are generated in a stationary shock structure. In this context we favor a co-rotating interaction region (CIR) and present a phenomenological model for X-rays from a CIR structure. We show that a CIR has the potential to account simultaneously for the X-ray variability and constraints provided by the spectral analysis. Ultimately, the viability of the CIR model will require both intermittent long-term X-ray monitoring of WR 6 and better physical models of CIR X-ray production at large radii in stellar winds.Comment: to appear in Ap

Corpora Caelestia: A Movement Opera

Corpora Caelestia: A Movement Opera is the written thesis prepared in conjunction with a performance that took place in October 2019. A requirement for the MFA in Dance at the University of Maryland, this performance crossed genres by blending dance and music. This paper outlines the performance from conception until completion, placing it within an experimental tradition of interdisciplinary work beginning in 1950s-60s New York. This written thesis articulates and engages two overarching concepts central to the thesis performance: dance as a practice of listening and dance as a path to transcendence. Each exploration surveys a history of its subject and uses the performance of Corpora Caelestia: A Movement Opera as a site of analysis to support a claim. First, I argue that postmodern dance improvisation can act as a practice of listening. Second, I defend the claim that transcendent encounters are desirable and possible through contemporary dance performances

Study of Organizational Knowledge Retention Practices in the Utilities

One key to the successful and long-term survival of an organization involves knowledge capture and retention. The knowledge may include company secrets, lessons learned, and hard-earned best-practices that are lost, forgotten, or disorganized in the event of staff loss or early retirement. In the United States, the aging workforce poses a specific difficulty vis a vie utility workers. Many are quickly approaching retirement and operations staff are heavily impacted by this movement. Properly capturing and retaining employee’s tacit knowledge is a labor-intensive task as it is usually transferred through personal observation with demonstration, mentors, apprenticeships, or on-the-job training. Consequently, articulating the tacit knowledge of an aging workforce is a challenging and time-consuming effort without proper preparation, oversight, and application of established knowledge retention strategies. It is advantageous for an organization to have implemented a fully encompassing knowledge management (KM) system during its inception; an exit interview is not enough. The development should begin concurrently with the hiring process, thus capturing newfound knowledge early. An accessible database for critical company data aids in knowledge retention, but even proven methods cannot capture all knowledge efficiently. The system is often overburdened by an abundance of information, which results in indistinguishable lessons and outdated instructions. It is crucial to have a balanced and working system for a functioning organization, but any implementation is preferable to none. This paper examined the methods and strategies utilized to capture and retain critical information within a local utility. Current operations staff and management have provided data by completing a Knowledge Management Capability Assessment. It was determined that the utility has a low operational knowledge management capability. This process has increased the understanding of current KM strategies and provides the local utility actionable data to improve upon or develop such strategies

Age modification of the relationship between C-reactive protein and fatigue: findings from Understanding Society (UKHLS)

Background: Systemic inflammation may play a role in the development of idiopathic fatigue, that is, fatigue not explained by infections or diagnosed chronic illness, but this relationship has never been investigated in community studies including the entire adult age span. We examine the association of the inflammatory marker C-reactive protein (CRP) and fatigue assessed annually in a 3-year outcome period for UK adults aged 16–98. Methods: Multilevel models were used to track fatigue 7, 19, and 31 months after CRP measurement, in 10 606 UK individuals. Models accounted for baseline fatigue, demographics, health conditions diagnosed at baseline and during follow-up, adiposity, and psychological distress. Sensitivity analyses considered factors including smoking, sub-clinical disease (blood pressure, anaemia, glycated haemoglobin), medications, ethnicity, and alcohol consumption. Results: Fatigue and CRP increased with age, and women had higher values than men. CRP was associated with future self-reported fatigue, but only for the oldest participants. Thus, in those aged 61–98 years, high CRP ( > 3 mg/L) independently predicted greater fatigue 7, 19, and 31 months after CRP measurement [odds ratio for new-onset fatigue after 7 months: 1.88, 95% confidence interval (CI) 1.21–2.92; 19 months: 2.25, CI 1.46–3.49; 31 months: 1.65, CI 1.07–2.54]. No significant longitudinal associations were seen for younger participants. Conclusions: Our findings support previously described CRP–fatigue associations in older individuals. However, there are clear age modifications in these associations, which may reflect a contribution of unmeasured sub-clinical disease of limited relevance to younger individuals. Further work is necessary to clarify intervening processes linking CRP and fatigue in older individuals

Development of a high-speed, reciprocating electrostatic probe system for Hall thruster interrogation

The use of electrostatic probes to measure local plasma parameters inside the discharge chamber of a Hall thruster presents significant difficulties. The high-temperature, dense plasma, and Hall current in the accelerating channel heat the probe rapidly causing ablation of probe material, which perturbs thruster operation and reduces probe lifetime. Results are presented which show the extent of perturbation to discharge current, cathode potential, and thrust for the case where probe material is ablated. A simple thermal model of probe material heating is developed and ablation times for a typical probe configuration are presented. Using the results of the thermal model, a high-speed axial reciprocating probe (HARP) system was developed to enable probe survival and reduce thruster perturbations during interrogation of the discharge chamber of a Hall thruster. Results using the HARP system are presented showing a significant reduction in thruster perturbation. The results also indicate that a mechanism other than material ablation is contributing to perturbation of the thruster. Based on emissive probe data, the tungsten conductor appears to provide a low impedance path between magnetic field lines, enhancing electron transport to the anode. © 2000 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70820/2/RSINAK-71-11-4131-1.pd

Collaborations in Liberal Arts Colleges in Support of Digital Humanities

The field of digital humanities has been rapidly expanding over the course of the last decade. As such, academic institutions have been working to identify ways of supporting these new endeavors in a time of economic struggles. The Digital Humanities Initiative (DHi) at Hamilton College was conceived as one possible model of supporting digital humanities scholarship at a liberal arts institution. The DHi model relies heavily on collaboration among different teams in the Library and Information Technology Services across campus, and with institutions across the United States. DHi also has international partnerships that promote its goals in research, learning, and public humanities. This chapter will describe the various collaborations of DHi and offer suggestions for how others can implement similar support models at their institutions

An investigation of fingerstick blood collection for pointof- care HIV-1 viral load monitoring in South Africa

Background: Viral load (VL) quantification is an important tool in determining newly developed drug resistance or problems with adherence to antiretroviral therapy (ART) in HIV-positive patients. VL monitoring is becoming the standard of care in many resource-limited settings. Testing in resource-limited settings may require sampling by fingerstick because of general shortages of skilled phlebotomists and the expense of venepuncture supplies and problems with their distribution.Objective: To assess the feasibility and ease of collecting 150 μL capillary blood needed for the use of a novel collection device following a classic fingerstick puncture.Methods: Patients were recruited by the study nurse upon arrival for routine ART monitoring at the Themba Lethu Clinic in Johannesburg, South Africa. Each step of the fingerstick and blood collection protocol was observed, and their completion or omission was recorded.Results: One hundred and three patients consented to the study, of whom three were excluded owing to the presence of callouses. From a total of 100 patients who consented and were enrolled, 98% of collection attempts were successful and 86% of participants required only one fingerstick to successfully collect 150 μL capillary blood. Study nurse adherence to the fingerstick protocol revealed omissions in several steps that may lower the success rate of capillary blood collection and reduce the performance of a subsequent VL assay.Conclusion: The findings of this study support the feasibility of collecting 150 μL of capillary blood via fingerstick for point-of-care HIV-1 VL testing in a resource-limited setting
