'Weak Center' gentrification and the contradictions of containment: deconcentrating poverty in Downtown Los Angeles
Full text linkThis case study of recent efforts to deconcentrate poverty within the Skid Row area of Los Angeles examines processes of ‘weak-center’ gentrification as it applies to a ‘servicedependent ghetto,’ thus filling two key gaps in prior scholarship. We document the collaboration between the government, business and development interests, and certainnon-profit agencies in this process and identify two key mechanisms of poverty deconcentration: housing/service displacement and the criminalization of low income residents. Following Harvey, we argue that these efforts are driven by pressures to find a ‘spatial fix’ for capital accumulation through Downtown redevelopment. This process has been hotly contested, however, illustrating the strength of counter-pressures to gentrification/poverty deconcentration within ‘weak-center’ urban areas
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Carcinopsida Casey. There 1916
No full textSubgenus Carcinopsida Casey Type Species. Paromalus opuntiae LeConte. Designated by Mazur (1984). Diagnosis and Comparison with Relatives. Taxa of this subgenus are characterized by the formation of individual ground punctures by a cluster or row of 3–4 micropunctures (Fig. 6), a tristriate lateral disc of the first abdominal ventrite (Fig. 2E), the continuation of the fourth dorsal elytral stria to the base without strongly arching toward the sutural stria, and an unmodified pygidium. The state of the ground punctation is shared with at least some members of the paromaline genus Xestipyge Marseul, but the latter two characters serve to distinguish Carcinopsida from these. Wenzel (in an unpublished key) compared a “sp. # 46” to C. opuntiae, reporting that it has the same ground punctation as C. opuntiae but “different elytral striae [and] only two lateral abdominal striae...”. Unfortunately, specimens labeled with a “46” or matching this description could not be found among the histerids at the Field Museum, where Wenzel’ s unfinished projects are housed. Geographic Distribution and Natural History. Two species are distributed from California, Arizona, and southern Texas to northern Mexico and the Baja California Peninsula. They are associated with the necroses of a diversity of cacti and the decaying basal stems of plants in the subfamilies Agavoideae and Nolinoideae.Published as part of Reese, Ellen M. & Swanson, Alexander P., 2017, A Review of the CactophilicCarcinopsMarseul (Coleoptera: Histeridae) of the Sonoran Desert Region, with Descriptions of Six New Species, pp. 159-190 in The Coleopterists Bulletin 71 (1) on page 181, DOI: 10.1649/0010-065X-71.1.159, http://zenodo.org/record/536267
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
