Performing heritage: the use of live 'actors' in heritage presentations

This paper investigates the phenomenon of 'living history' presentations of heritage, using live 'actors' to portray historical characters. Its aim is to discuss these presentations in the context of what may be understood as 'heritage', and of the nature of 'performance'. Four case studies of heritage sites, each important as a tourist attraction, have been selected for detailed study, together with a number of other examples of heritage performance. It is clear from the empirical work that different performance strategies are employed within the heritage industry and by individual 'actors'. Most of the performers take part as a leisure activity, and many do not consider themselves to be 'performing' at all. The greatest concern of participants lies in the degree of authenticity of the performance. Through 'living history', the 'actors' are drawn into an experience of heritage which has real meaning for them, and which may contribute both to a sense of identity and to an enhanced understanding of society, past and present. The popularity of such presentations with visitors also indicates that similar benefits are perceived by the 'audience'

Low-Bandwidth and Non-Compute Intensive Remote Identification of Microbes from Raw Sequencing Reads

Cheap high-throughput DNA sequencing may soon become routine not only for human genomes but also for practically anything requiring the identification of living organisms from their DNA: tracking of infectious agents, control of food products, bioreactors, or environmental samples. We propose a novel general approach to the analysis of sequencing data in which the reference genome does not have to be specified. Using a distributed architecture we are able to query a remote server for hints about what the reference might be, transferring a relatively small amount of data, and the hints can be used for more computationally-demanding work. Our system consists of a server with known reference DNA indexed, and a client with raw sequencing reads. The client sends a sample of unidentified reads, and in return receives a list of matching references known to the server. Sequences for the references can be retrieved and used for exhaustive computation on the reads, such as alignment. To demonstrate this approach we have implemented a web server, indexing tens of thousands of publicly available genomes and genomic regions from various organisms and returning lists of matching hits from query sequencing reads. We have also implemented two clients, one of them running in a web browser, in order to demonstrate that gigabytes of raw sequencing reads of unknown origin could be identified without the need to transfer a very large volume of data, and on modestly powered computing devices.

Supporting Scholars in Training: A User Needs Survey of a Graduate Study Space

A separate study area reserved for faculty and graduate students was established at Auburn University’s Draughon Library in 2008, but, for many years, there was no formal effort to study the use of the space. In 2016, recognizing that the needs of these user groups differ in significant respects from those of undergraduates, the presenters developed a questionnaire to gather information on the faculty and graduate students using the area and the adequacy of the space to support their work practices. For two weeks in the summer and four weeks in the fall of 2016, users visiting the area were asked to complete a survey that asked about their departmental/college affiliation, how often they used the space and the length of time they spent there, the type of work they were doing, and whether anything was preventing them from accomplishing their goals. The questionnaire also invited users to provide additional feedback they had about the space. The presenters will share the results of their research, the steps they took to improve the study area based on the feedback they received, and the campus partnerships they forged to support the graduate “scholars in training” who are the primary users of this space. At the outset of the talk, audience members will be asked to lend their voices to the question of what elements are most important to library environments that aim to facilitate the academic work of graduate students

Narrowing the Farm-to-Plate Knowledge Gap through Semiotics and the Study of Consumer Responses Regarding Livestock Images

It has been suggested that a farm-to-plate knowledge gap exists between farmers and consumers. In addition, previous studies have concluded that U.S. citizens do not have accurate knowledge or perceptions about agriculture. It is thought that this absence of knowledge and existing misconceptions may be due to the images consumers see regularly through the media. In this research study, researchers used a directly administered questionnaire to evaluate consumers’ responses regarding the comparison of two livestock images. The study was conducted at the 2009 Ohio State Fair. Through voluntary participation, research participants answered questions regarding their perceptions of traditional and conventional livestock housing methods by viewing two images. In addition, participants were asked to justify each of their responses through oral reasoning. Questionnaires were completed by 508 participants, of which 502 were deemed usable. Results indicate participants are somewhat knowledgeable about livestock housing methods, but the perceptions and justifications of the respondents are not always accurate. The results also indicate agricultural images, as well as images regularly seen in the media, may influence such perceptions. In order to narrow the farm-to-plate knowledge gap, it is important for the agriculture industry to effectively improve the knowledge and perceptions of agriculture amongst consumers

The JCMT Gould Belt Survey: A First Look at the Auriga–California Molecular Cloud with SCUBA-2

We present 850 and 450 μm observations of the dense regions within the Auriga–California molecular cloud using SCUBA-2 as part of the JCMT Gould Belt Legacy Survey to identify candidate protostellar objects, measure the masses of their circumstellar material (disk and envelope), and compare the star formation to that in the Orion A molecular cloud. We identify 59 candidate protostars based on the presence of compact submillimeter emission, complementing these observations with existing Herschel/SPIRE maps. Of our candidate protostars, 24 are associated with young stellar objects (YSOs) in the Spitzer and Herschel/PACS catalogs of 166 and 60 YSOs, respectively (177 unique), confirming their protostellar nature. The remaining 35 candidate protostars are in regions, particularly around LkHα 101, where the background cloud emission is too bright to verify or rule out the presence of the compact 70 μm emission that is expected for a protostellar source. We keep these candidate protostars in our sample but note that they may indeed be prestellar in nature. Our observations are sensitive to the high end of the mass distribution in Auriga–Cal. We find that the disparity between the richness of infrared star-forming objects in Orion A and the sparsity in Auriga–Cal extends to the submillimeter, suggesting that the relative star formation rates have not varied over the Class II lifetime and that Auriga–Cal will maintain a lower star formation efficiency

“You Call that Meat?” Investigating Social Media Conversations and Influencers Surrounding Cultured Meat

Cultured meat has yet to reach store shelves but is nonetheless a growing issue for consumers, producers, and government regulators, many of whom have taken to social media to discuss it. Using a conceptual framework of social cognitive theory and issues management, this qualitative content analysis investigated social-media discourse surrounding the topic of cultured meat in the United States by describing the content of the discussion in late 2018 and identifying individual influencers and communities of influencers engaged in the discussion. Data were collected from Twitter using listening platform Sysomos MAP. The thematic analysis revealed eight themes: legality and marketing, sustainability, acceptance, business, animal concerns, science and technology, health concerns, and timeline, and indicated that conflicting views and questions about cultured meat exist among conversation participants. Top influencers included philanthropists, government officials, journalists and writers, and animal-welfare advocates. These influencers were grouped into four distinct communities based on interactions with each other and other users. The topics identified in the analysis provide insight into ways in which communicators can enter these conversations, and influencer communities represent groups of users whose broad reach could more easily transmit pro-agriculture messages

The JCMT Gould Belt Survey: Evidence for radiative heating in Serpens MWC 297 and its influence on local star formation

We present SCUBA-2 450micron and 850micron observations of the Serpens MWC 297 region, part of the JCMT Gould Belt Survey of nearby star-forming regions. Simulations suggest that radiative feedback influences the star-formation process and we investigate observational evidence for this by constructing temperature maps. Maps are derived from the ratio of SCUBA-2 fluxes and a two component model of the JCMT beam for a fixed dust opacity spectral index of beta = 1.8. Within 40 of the B1.5Ve Herbig star MWC 297, the submillimetre fluxes are contaminated by free-free emission with a spectral index of 1.03+-0.02, consistent with an ultra-compact HII region and polar winds/jets. Contamination accounts for 73+-5 per cent and 82+-4 per cent of peak flux at 450micron and 850micron respectively. The residual thermal disk of the star is almost undetectable at these wavelengths. Young Stellar Objects are confirmed where SCUBA-2 850micron clumps identified by the fellwalker algorithm coincide with Spitzer Gould Belt Survey detections. We identify 23 objects and use Tbol to classify nine YSOs with masses 0.09 to 5.1 Msun. We find two Class 0, one Class 0/I, three Class I and three Class II sources. The mean temperature is 15+-2K for the nine YSOs and 32+-4K for the 14 starless clumps. We observe a starless clump with an abnormally high mean temperature of 46+-2K and conclude that it is radiatively heated by the star MWC 297. Jeans stability provides evidence that radiative heating by the star MWC 297 may be suppressing clump collapse.Comment: 24 pages, 13 figures, 7 table

Should livestock images provide historical reference or modern reality? An examination of the Influence of Livestock Communication on Attitude.

The livestock industry has repeatedly struggled to effectively communicate livestock care and handling practices in order to promote awareness and acceptance. Many consumers still hold on to the historically picturesque view of production agriculture instead of the modern reality. It is necessary for the industry to identify how much is too much to tell or show consumers. Therefore, this study sought to understand the influence of two communication treatments on attitudes toward livestock care and use. Elaboration Likelihood Model (ELM) served as the theoretical framework for this study. A sample of 1,049 respondents was obtained through non-probability sampling. To fulfill the purpose of this study, the development of an online survey was informed by ELM and measured prior beliefs, personal involvement, and knowledge. An experimental treatment, consistent with persuasive communication within ELM, presented respondents with one of two images of cage-free egg laying housing and accompanying text. One image could be described as “historically picturesque” and the other as “modern reality.” Attitude toward livestock care and use was measured after exposure to one of the images. Respondents held favorable prior beliefs, demonstrated neutral involvement, and answered three or less knowledge questions correctly. Respondents exposed to the modern reality treatment displayed slightly lower attitudes than those exposed to the historically picturesque treatment. The results indicated that both prior beliefs and image exposure had a significant impact on attitude, while personal involvement was not found to be significant

Bridging the Skills Gap: A Boot Camp for Graduate Students

Graduate students have information literacy needs that are distinct from those of undergraduates and faculty. As they prepare for academic and professional careers, graduate students must acquire skills needed to conduct scholarly research; organize and work with information sources; and effectively communicate research findings. These competencies are often not addressed by the curricular content of their graduate programs. To help bridge this gap, library faculty at a public land grant university organized a one-day research skills boot camp. The boot camp’s workshops include sessions on locating scholarly sources, writing literature reviews, organizing citations, managing data, creating engaging presentations, and increasing scholarly impact. Student response to the weekend boot camp has been overwhelmingly positive, with 550 students attending six boot camps during 2019-2020. The presenters will share results from two studies they conducted to better understand the research needs of graduate students. The first study examines survey feedback from boot camp participants, and the second analyzes focus group interviews to gain additional insight about two subgroups of interest: international graduate students and non-traditional graduate students. Panel attendees interested in sponsoring a similar event will receive practical tips on event programming and registration, branding and promotion, and assessment. The presenters will also report on successful collaborations with campus partners focused on student success (e.g., graduate school, writing center, and teaching and learning center)
