Oral History Interview with Hermi Salas, February 14, 2005
No full textInterview with Oral interview with Hermi Salas, a U. S. Marine during World War II. Salas was assigned to the Third Marine Division and was present for the invasion of Guam in the Mariana Islands. He was wounded on Guam and evacuated to a hospital ship, the USS Solace. He also participated in the Iwo Jima landings. After a few weeks at Iwo Jima, Salas was wounded again and placed aboard the USS Solace. He discusses his experiences in the hospital recovering from the wounds he received in the Battle of Iwo Jima. Eventually, he made his way back to San Antonio. He also discusses a brief leave at home before he reported to prison guard duty in Corpus Christi. Upon being discharged after the war, Salas went to radio school and worked at Kelly Air Force Base in the Civil Service

MATERIAL. — MWQ, early Miocene, Burdigalian, Orleanian, MN 4: 1/2001 Turtle Joint: One posterior trunk vertebra (Pal. 1448). DESCRIPTION Trunk vertebra The only preserved trunk vertebra is almost complete with partial damage to the large paradiapophyses, the cranial margin of the zygosphene and the caudal margin of the condyle. In lateral view, the neural spine rises at about the level of the zygosphenal base. The cranial margin of the neural spine is inclined caudally with a rounded anterodorsal margin. The articular surfaces of the zygosphene are widely oval. The short interzygapophyseal ridges are rather sharp. The small lateral foramina, situated close below the interzygapophyseal ridges, do not sit within depressions. The short and dorsally bent subcentral ridges are well-developed, especially in the anterior half of the centrum. In dorsal view, the partially damaged prezygapophyseal articular facets were originally broadly subtriangular to oval in outline. The prezygapophyseal processes are rather short (about a quarter of the prezygapophyseal facets length). The zygosphene was almost straight with small lateral lobes; however, the medial part of the zygosphenal lip is rather damaged in the preserved specimen. The dorsal margin of the neural spine becomes thick towards its caudal margin. The caudal margin of the neural arch forms a relatively shallow notch. In ventral view, the haemal keel is laterally wide with a rounded ventral surface. The subcentral foramina are rather small and developed on either side of the haemal keel base. The subcentral grooves are wide and deep. The postzygapophyseal articular facets are subrectangular in shape. In cranial view, the prezygapophyses are tilted slightly dorsally. Prezygapophyseal articular facets are situated high above the neural canal base roughly at the level of the dorsal margin of the lateral sinuses. The cranial margin of the zygosphene is slightly concave with strongly build lateral sinuses and a rather thin central part. The neural arch is vaulted. The neural canal is rounded with rather wide and shallow lateral sinuses. Depressions are developed on either side of the slightly dorsoventrally depressed cotyle. The paracotylar foramina are absent. In caudal view, the zygantrum is wide. The condyle is slightly depressed dorsoventrally. The vertebral dimensions are as follows (Pal. 1448): cl: = 5.19 mm; naw = 6.73 mm; cl/naw = 0.77. REMARKS The massive structure of vertebra, the cl/naw ratio <1, the relatively large dimensions, and the absence of paracotylar foramina as well as the relatively slender structure of the zygosphenal rim support the assignment to the subfamily Boinae. The single preserved vertebra resembles that of the genus Bavarioboa by the almost straight cranial margin of the zygosphenal lip in dorsal view, as well as the dorsally thickened neural spine that is typical for the posterior trunk vertebrae of Bavarioboa hermi (see Szyndlar & Rage 2003). B. ultima Szyndlar & Rage, 2003 from the German late early Miocene Rothenstein 13 locality (late Burdigalian, MN 5), originally assigned to B. hermi by Szyndlar & Schleich (1993), differs mainly by the lower neural spine as well as longer prezygapophyseal processes (Szyndlar & Rage 2003).Published as part of Ivanov, Martin, Čerňanský, Andrej, Bonilla-Salomón, Isaac & Luján, Àngel Hernández, 2020, Early Miocene squamate assemblage from the Mokrá-Western Quarry (Czech Republic) and its palaeobiogeographical and palaeoenvironmental implications, pp. 343-376 in Geodiversitas 42 (20) on pages 356-357, DOI: 10.5252/geodiversitas2020v42a20, http://zenodo.org/record/444756
Effect of humain activities in south lake of Tunis on free nematod communities structure in autumn
No full textThe answer of the free nematode populations to the physico - chemical state of “ lake ” south Tunis has been studied in autumn 96 from 10 sampling sites. Their very weak specific diversity (Hermi, 2001) and the non selective détritivorous proliferation (1B) bound to the strong contents in recorded organic matter (Hermi, 2001) revealed the sensitivity of nematodes to the eutrophication and nutritionnal pollution. According to several interrelationships calculations, the waters saturation in oxygen, their contents in abeyance matter and in nitrogen as well as the sediments granulometry and their contents in certain heavy metals, appeared the most lagoonar determining parameters.
Otherwise, the answer of nematofaunistic communities living in South lake was very dependent of the state of deterioration of the sampling site. Thus, the weakest and trophic diversities were observed s in the most enclose western sector, there where predominated Theristus flevensis, a species able to tolerate strong contents in organic matter. On the other hand, the station relatively less eutrophic of the Radès Channel were revealed the more varied as well according to trophic index that according to the number of nematode species inventoried.La réponse des peuplements de nématodes libres à l’état physico-chimique du lac sud de Tunis a été étudiée en automne 96 à partir de 10 sites de prospection. Leur diversité spécifique très faible (Hermi, 2001) et la prolifération des détritivores non sélectifs (1B) liée aux fortes teneurs en matière organique enregistrées (Hermi, 2001) ont révélé la sensibilité des nématodes à l’eutrophisation et à la pollution nutritionnelle constatées. D’après plusieurs calculs de corrélations, la saturation des eaux en oxygène, leurs teneurs en matière en suspension et en azote ainsi que la granulométrie des sédiments et leurs teneurs en certains métaux lourds, sont apparus les paramètres lagunaires les plus déterminants.Par ailleurs, la réponse des communautés nématofaunistiques peuplant le lac sud a été très dépendante de l’état de dégradation du site d’échantillonnage. Ainsi, les plus faibles diversités spécifique et trophique ont été observées au niveau du secteur occidental le plus confiné, Theristus flevensis, une espèce capable de tolérer de fortes teneurs en matière organique y étant largement prédominante. Par contre, la station relativement moins eutrophisée du canal de Radès s’est révélée la plus diversifiée aussi bien d’après l’index trophique qu’en fonction du nombre d’espèces de nématodes inventoriés.PublishedAnthropisation, Nématodes libres, lac sud de Tuni
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Get PDFWe 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
Magnitude estimation in humans
Get PDFAnyone who has climbed a mountain before knows that the perceived distance walked depends on more than just its physical length. This intriguing relationship between physical and
experienced magnitudes has fascinated researchers across various disciplines for more than 200 years. Part of the enthusiasm is driven by the fact that, although magnitudes, as well as the sensory organs with which we measure them, differ in so many ways, there are unifying principles in behavior common to all types of magnitudes estimated. In this thesis, the general characteristics of human magnitude estimation are studied in the case of visual path integration. The aim is to clarify the role of a-priori knowledge on the estimate of magnitude and to provide a unifying mathematical framework that explains the behavior. In particular, we investigated human linear and angular displacement estimation in different experimental situations with varying experience-dependent and abstract a-priori knowledge. We find systematic behavioral characteristics that are omnipresent
in magnitude estimation studies, like the range effect, the regression effect or scalar variability. These characteristics are explained by a general model that combines a logarithmic
scaling of magnitudes according to the Weber-Fechner law with the concept of Bayesian inference. The model incorporates apriori
knowledge about the stimulus and updates this knowledge on a trial-by-trial basis. The resulting iterative Bayesian estimation accounts for the aforementioned behavioral characteristics
and provides a link between the two most well-known laws in psychophysics: the Weber-Fechner and Stevens’ powerlaw. This work provides substantial evidence that magnitude estimation is not purely driven by sensation but underlies perceptual estimation processes that exploit and incorporate different types of information sources, in particular short-term prior experience. The proposed mathematical framework is likely applicable to magnitude estimation across different modalities and consequently contributes to a unifying account of the behavior
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
