Feng Huang carved horn
No full textThis horn carving is of the famous Feng Huang, which is known to westerners as the Phoenix. Notice the long tail feathers and distinctive head shape. This bird is considered the head of the feathered kingdom in Chinese culture. It is considered second of the four auspicious animals, behind the dragon and ahead of the unicorn and tortoise. As the Emperor is associated with the dragon, the phoenix is associated with the Empress. It is a symbol of harmony and peace, as it hides in times of war. It is perched on a tree, which may be the legendary wu t'ung tree. This is apparently the only tree the phoenix will come from the sky to sit on. The bottom portion of the carving has been hollowed out. This has made the object very delicate in that region. Notice the very good detail of the feathers along its back and tail. The brownish-red color of the horn probably means this object was carved from water buffalo horn. It seems to have aged at least over 100 years.Qing dynast

Etymology:―The specific epithet refers to the habitat of the new species. Phenology:―Flowering from March to April, fruiting from July to October. Distribution and habitat:― Vernicia calcicola is currently known in a small area near Sino-Vietnam border between Guangxi and Cao Bang provinces. It grows on limestone slopes in primary or secondary broad-leaved evergreen forests, between 588 and 973 m a.s.l., associated with Itoa orientalis Hemsl., Sterculia euosma W. W. Smith, Wrightia sikkimensis Gamble, Toxicodendron wallichii var. microcarpum C. C. Huang ex T. L. Ming, Diospyros siderophylla H. L. Li, Nephrolepis cordifolia (L.) C. Presl. Taxonomic relationships:―Among the three widely cultivated species in China and Japan, V. calcicola most closely resembles V. fordii in the tree shape and stipules shape, the main difference between the two species are the glands at the apex of petiole (columnar, connate and stalked vs cushion-shaped, sessile), calyx (apex apiculate, slightly (2–)3 or 4-fid vs apex obtuse, 2 or 3-fid), florescences (unisexual vs bisexual), ovary indumentum (glabrous vs pubescent) and fruit stalk (stout vs slender). Besides, the stems of young trees thicker at base probably to adapt the water shortage in limestone areas (Figs. 2K). Although the four Vernicia species are closely related, there are still many morphological differences between them, such as the stipules, glands at the apex of the petiole, inflorescence, fruit stalk and fruit surface (Figs. 2 & 3). Details of the morphological differences between V. calcicola, V. fordii, V. Montana (1790: 587) and V. cordata (1967: 394) are showed in Table1.Published as part of Nong, Dong-Xin, Hu, Ren-Chuan, Huang, Yun-Feng & Yu, Li-Ying, 2023, Vernicia calcicola (Euphorbiaceae), a new species from limestone areas of Guangxi, China, pp. 205-210 in Phytotaxa 587 (2) on pages 205-208, DOI: 10.11646/phytotaxa.587.2.10, http://zenodo.org/record/773179

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
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

Abstraction
This study investigates the senior high school students’ understanding of DC circuit analogies by their reasoning of DC circuit conceptions.
Four analogy models were studied, including "Water tank model", "People with loading model", "Closed water-circuit model", and "Train model". The sample included 122 10th grade students and 120 12th grade students from 6 different classes. All students had studied the topic of DC circuits before. They were required to read the "DC circuits analogies material", and then take a test. The test included the misconceptions test designed to diagnose students’ misconceptions and the level-explaining item to let students judge how accurate each model can be used to explain their answers. The evaluation of students has been transformed into grid on the basis of Repertory Grid Technique（RGT）, and compared with the grid completed through literature review and experts, then calculated the "Analogy reasoning score" by RGT "EXCHANGE" theory. Finally, students finished the questionnaire to make the overall evaluation of the four models. After the test, interviewing with some students to make sure the conceptions they had and the reasons of evaluation.
Major findings were summarized as the following︰
1. The 12th grade students were better than 10th grade students except in "local reasoning", "battery producing constant electric current", "short-circuit" misconceptions etc…
2. In the closed water circuit model and train model, the 12th students’ reasoning are better than 10th grade students, the other models are equal.
3. The misconceptions were mapping with some attributes of the four models students perceived.
4. The evaluation of analogy would change with the reasoning level of the analogy.
5. Some students who had "correct concepts" but didn't understand the analogy was due to their not understanding of micro conception of circuits.
6. When we changed the presenting order of the closed water circuit model, which is the least understanding one for 10th grade students. It will affect their understanding of the model, but such situation didn’t occur in the 12th grade students.
