Can museums find male or female audiences online with YouTube?

This is an accepted manuscript of an article published by Emerald Publishing Limited in Aslib Journal of Information Management on 31/08/2018, available online: https://doi.org/10.1108/AJIM-06-2018-0146 The accepted version of the publication may differ from the final published version.Purpose: This article investigates if and why audience gender ratios vary between museum YouTube channels, including for museums of the same type. Design/methodology/approach: Gender ratios were examined for public comments on YouTube videos from 50 popular museums in English-speaking nations. Terms that were more frequently used by males or females in comments were also examined for gender differences. Findings: The ratio of female to male YouTube commenters varies almost a hundredfold between museums. Some of the difference could be explained by gendered interests in museum themes (e.g., military, art) but others were due to the topics chosen for online content and could address a gender minority audience. Practical implications: Museums can attract new audiences online with YouTube videos that target outside their expected demographics. Originality/value: This is the first analysis of YouTube audience gender for museums

Kepler constraints on planets near hot Jupiters

We present the results of a search for planetary companions orbiting near hot Jupiter planet candidates (Jupiter-size candidates with orbital periods near 3 d) identified in the Kepler data through its sixth quarter of science operations. Special emphasis is given to companions between the 2∶1 interior and exterior mean-motion resonances. A photometric transit search excludes companions with sizes ranging from roughly two-thirds to five times the size of the Earth, depending upon the noise properties of the target star. A search for dynamically induced deviations from a constant period (transit timing variations) also shows no significant signals. In contrast, comparison studies of warm Jupiters (with slightly larger orbits) and hot Neptune-size candidates do exhibit signatures of additional companions with these same tests. These differences between hot Jupiters and other planetary systems denote a distinctly different formation or dynamical history

The low-frequency radio catalog of flat spectrum sources

A well known property of the gamma-ray sources detected by COS-B in the 1970s, by the Compton Gamma-ray Observatory in the 1990s and recently by the Fermi observations is the presence of radio counterparts, in particular for those associated to extragalactic objects. This observational evidence is the basis of the radio-gamma-ray connection established for the class of active galactic nuclei known as blazars. In particular, the main spectral property of the radio counterparts associated with gamma-ray blazars is that they show a flat spectrum in the GHz frequency range. Our recent analysis dedicated to search blazar-like candidates as potential counterparts for the unidentified gamma-ray sources (UGSs) allowed us to extend the radio-gamma-ray connection in the MHz regime. We also showed that below 1 GHz blazars maintain flat radio spectra. Thus on the basis of these new results, we assembled a low-frequency radio catalog of flat spectrum sources built by combining the radio observations of the Westerbork Northern Sky Survey (WENSS) and of the Westerbork in the southern hemisphere (WISH) catalog with those of the NRAO Very Large Array Sky survey (NVSS). This could be used in the future to search for new, unknown blazar-like counterparts of the gamma-ray sources. First we found NVSS counterparts of WSRT radio sources and then we selected flat spectrum radio sources according to a new spectral criterion specifically defined for radio observations performed below 1 GHz. We also described the main properties of the catalog listing 28358 radio sources and their logN-logS distributions. Finally a comparison with with the Green Bank 6-cm radio source catalog has been performed to investigate the spectral shape of the low-frequency flat spectrum radio sources at higher frequencies.Comment: 10 pages, 10 figures, 1 table, ApJS published in 2014 (pre-proof version uploaded

Mandan and Hidatsa Music

This ethnographic study, dated January 1, 1924, sponsored by the Smithsonian Institution Bureau of Ethnography presents information about the social and ceremonial significance of music to the Mandan and Hidatsa tribes as collected by anthropologist Frances Densmore from the Fort Berthold Reservation in 1912, 1915, and 1918. This study was conducted at the behest of the State Historical Society of North Dakota. The collection includes a catalogue of songs, a description of customs, legends, folk tales, societies, and photographs of musical instruments, some tribal members, earth lodges and other structures.https://commons.und.edu/indigenous-gov-docs/1002/thumbnail.jp

Anthropological Papers, No. 51: Observations on Some Nineteenth-Century Pottery Vessels from the Upper Missouri

Published as a bundle of anthropological works sponsored by the Smithsonian Institution Bureau of American Ethnology, paper number 51 is an analysis of 25 pottery specimens from the Upper-Missouri area. These specimens are attributed to the Lewis and Clark expedition, to army personnel, and to other travelers. The origin of the pottery is uncertain, though there are indications that some pieces may have originated from Fort Berthold, Fort Buford, and Fort Stevenson. The paper offers background on pottery making in the Upper-Missouri, noting that the Arikara, Mandan, and Hidatsa tribes made paddle-and-anvil pottery rather than coil pottery. Further background observations help illuminate the possible history of the pottery specimens found. The paper includes illustrations and a map.https://commons.und.edu/indigenous-gov-docs/1104/thumbnail.jp

Anthropological Papers, No 45: Archeological Materials from the Vicinity of Mobridge, South Dakota

Published as a bundle of anthropological works sponsored by the Smithsonian Institution Bureau of American Ethnology, paper number 45 is a description of findings from an excavation of four burial sites which are presumed to be associated with village sites from Grand River and Elk Creek (located north of Morbridge, South Dakota). Excavation was completed by Matthew W. Sterling in 1923, described here by Waldo R. Wedel. These sites are documented as Arikara territory. The paper begins with an overview of Arikara history from 1717 forward as documented by European explorers, followed by a description of the graves excavated and the artifacts found. The report contains illustrations, tables summarizing excavation contents, and a map.https://commons.und.edu/indigenous-gov-docs/1008/thumbnail.jp
