Perbandingan Keragaman Jenis Burung Tahun 2018 Dan 2023 Di Taman Hutan Kota Kaombona Palu Provinsi Sulawesi Tengah: Comparison of Bird Species Diversity in 2018 and 2023 in Kaombona City Forest Park, Palu, Central Sulawesi Province
No full textKeanekaragaman jenis burung di Taman Hutan Kota Kaombona Palu antara tahun 2018 dan tahun 2023 memiliki perbedaan yang signifikan diduga keanekaragaman jenis di area ini dari beberapa tahun terakhir mengalami perubahan habitat, diduga disebabkan faktor-faktor fisik lingkungan seperti aktivitas manusia, kondisi tanah, air, temperatur, cahaya matahari, serta faktor-faktor biologis yang meliputi vegetasi dan satwa lainnya. Tujuan penelitian ini yaitu melihat perbedaan komposisi jenis burung antara tahun 2018 dan 2023, sebagai sumber informasi tentang keanekaragaman jenis burung dan populasi burung di hutan Kota Kaombona Palu. Sedangkan data keanekaragaman burung diambil dengan metode titik hitung (point count) dengan radius 50 m dan jarak 100 m antara tiap titik. Hasil indeks Keanekaragaman Shanon (H') tahun 2018 yaitu H' = 2.463 dan hasil indeks keanekaragaman Shanon (H') tahun 2023 yaitu H' = 4.34. Selain itu Beberapa jenis-jenis burung yang teramati di habitat ini sering bergerombol saat mencari pakan, keberadaan satwa burung pada suatu habitat sangat erat hubungannya dengan faktor-faktor fisik lingkungan seperti tanah, air, temperatur, cahaya matahari, serta faktor-faktor biologis yang meliputi vegetasi dan satwa lainnya
NILAI KOEFISIEN LIMPASAN (C) SUB DAS TARIPA DI KECAMATAN TOAYA KABUPATEN DONGGALA PROVINSI SULAWESI TENGAH
Full text linkThe coefficient of surface runoff (denoted by C), in this case is strongly influenced by the watershed conditions such as gradients, soil infiltration, land use and surface water deposits. This value of C can be used as an indicator in assessing the level of damage of the watershed. Forest and land of Taripa sub-watershed in taripa village is functioned as a regulator of hydrology and also a source of water for irrigation in Sumari village, Lero and Toaya. The Taripa sub-watershed has a very important role for life. To know the tendency of hydrological characteristic of Taripa sub-watershed is better or worse, it can be investigated by observing the tendency of Taripa sub-watershed flow by calculating the runoff coefficient value (C). To calculate the runoff coefficient value, firstly the water discharge and rainfall is analyzed.This research was conducted with the aim to know the value of runoff coefficient (C) and the its function (C) of Taripa sub watershed in Taripa Village of Donggala Regency of Central Sulawesi Province. This research was planned to be implemented from September 2016 until April 2017 in Taripa Village of Toaya District of Donggala Regency, Central Sulawesi Province. The results of this study are expected to be an early information of the condition of land capability of sub-watershed Taripa in order to control the water by knowing the runoff coefficient value (C). Based on the results of the research, the daily debit value is the total of daily debit, 523,048,50 m3 reduced by the Base Flow, 78,697 m3 equals to 442,157,5 m3 with rainfall totaled 163 mm, where the highest rainfall happened on Tuesday, June 13, 65 mm, and on Wednesday, 21 June, 27 mm. The value of runoff coefficient (C) of Taripa river, based on the calculation, is 0.37. This value illustrates that the hydrologic system in the Taripa sub watershed of Taripa Village is in moderate level
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
