Figures Don't Lie: Spatial Humanities and Technology as Critical Thinking Tools
No full textThis presentation demonstrates the potential use of spatial humanities as both a critical thinking exercise and a computational tool in digital humanities pedagogy. “Figures Don’t Lie” presents a map of the United States that labels each state as a foreign nation according to the correlation between the GDPs of each state and their assigned countries. The map may spark classroom discussions about a range of humanities topics. Revealing the map’s underlying data shows how facts can be spun and helps students understand how the “facts” presented in the media may not be what they appear.Presented at Rutgers University's "Digital Humanities Showcase: New Methods and New Media" on January 29, 2014 (New Brunswick, N.J.)
Calculating All That Jazz: Linking Technical Specifications to the Management of Digitization Projects
No full textThe purpose of this session is to educate librarians and archivists about the technical aspects of the digitization process and demonstrate how deeper understanding of those aspects can be used to evaluate the appropriateness of digitization standards, project scope, quality of digitization equipment and storage needs for digitization projects involving photographs and documents. Most scholarship on archival-quality digitization has focused on either elements of digital library project management or on technical specifications and how to digitize materials. "Calculating All That Jazz" focuses on presenting a formula for calculating digital storage space based on analog still images and documents, demonstrating how deeper understanding of the technical elements of digitization in the formula applies directly to crucial project management considerations
The workshop as the work: white anti-racism organising in 1960s, 70s, and 80s US social movements
No full textThis thesis explores the rise of anti-racism workshops developed by white activists in various United States social movements from the late 1960s through the mid-1980s. The shifting ideology of the black freedom movement in the late 1960s, from integration to Black Power, transformed white activists‘ place within racial justice struggles. While recent scholarship has begun to turn its attention towards whites‘ ongoing racial justice activities, one of the most radical and widespread of these efforts is consistently overlooked: anti-racism workshops. Increasingly prevalent from the late 1960s through to the diversity-trainings explosion of the 1990s, this thesis demonstrates that these workshops had their roots in the black freedom, women‘s liberation and gay liberation movements. White activists from these movements led these workshops in order to examine white racial domination and privilege within both leftist social movements and larger US society.
Analysing case studies from the black freedom, women‘s liberation and gay liberation/rights movements, this thesis explores the foundational assumptions of anti-racism workshops. It seeks to explain how and why these efforts sought to frame race and racism as issues of knowledge and consciousness and why such efforts constituted radical praxis. It is argued that early anti-racism workshops were pedagogical projects that sought to confront the racial ignorance that structured the lives of whites in the US, including progressives and their liberation movements. This thesis draws attention to the efficacy and power of these workshops in terms of their epistemological effects, in the transformations they brought about in whites‘ understanding, or awareness, of racial realities

Espousing Ezili: Images of a Lwa, Reflections of the Haitian Woman
No full textThis article examines the iconography of the two main female divinities in Haitian Vodou, Ezili Danto and Ezili Freda, using common chromolithographs of each personality. Images of the Ezilis are analyzed in the context of visual culture to discern how iconography informs viewers about the political position of Haitian women of the past and present. To realize this goal, the author addresses some of the complex dynamics that shaped the lives of colonial Haitian women as well as the contemporary factors affecting women's lives today.This article was originally published in Journal of Haitian Studies, http://www.research.ucsb.edu/cbs/publications/johs/Peer reviewe
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Crustal structure of the Southwest Indian Ridge at 66E: seismic constraints
No full textThe Southwest Indian Ridge represents a slow-spreading end-member of the global mid-ocean\ud
ridge system, and as such its structure places important constraints on models of melt supply\ud
and delivery from the mantle at ridges. We present results from a wide-angle seismic experiment\ud
conducted at the ridge axis at 66◦E, in a region that has comprehensive swath bathymetric,\ud
gravity and magnetic data coverage and where the full spreading rate is ∼12 mm yr−1.\ud
Based on these data, the experiment traversed four spreading segments. Crustal thickness and\ud
velocity structure were determined along three intersecting profiles each ∼100 km long using\ud
shots from a 10-gun, 71 L tuned airgun array towed at 15 m depth and fired at 40 s intervals,\ud
recorded on three ocean bottom hydrophones on each profile. OBH data show high-amplitude\ud
arrivals from oceanic Layer 2, lower-amplitude arrivals from Layer 3 and wide-angle reflections\ud
from the Moho. Forward modelling and inversion of traveltime picks from these data\ud
show that the crust consists of a 1.5–2.5-km-thick Layer 2 with a high velocity gradient and a\ud
0.5–3.0-km-thick Layer 3 with a low velocity gradient, and a crustal thickness of 2.2–5.4 km.\ud
Additional constraints on the models come from 2-D modelling of gravity data along the profiles,\ud
corrected for 3-D effects of off-line bathymetry. Along-axis, the thickness of Layer 2\ud
varies little, but Layer 3 is thick at segment centres and very thin at segment boundaries. Along\ud
a flowline profile, crustal thickness varies by up to 75 per cent from its minimum value in\ud
∼3 Myr. The reduced crustal thickness is consistent with observations from very slow-spreading\ud
ridge axes elsewhere and may be explained by conductive cooling of the upwelling mantle.\ud
The large along-axis variations in Layer 3 thickness indicate that magmatic accretion is focused\ud
at segment centres and melt is delivered to segment ends perhaps only by lateral dyke propagation.\ud
Flowline variations in crustal thickness may result from episodicity of melt supply on\ud
timescales of ∼3 Myr and by tectonic extension during amagmatic periods. Velocities at the\ud
top of Layer 2 are poorly correlated with crustal age based on magnetic anomalies, suggesting\ud
also that episodicity is decoupled between adjacent segments
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
