POLA SEBARAN POPULASI AREN (Arenga pinnata) BERDASARKAN KELAS PERTUMBUHAN DI DESA SANGTANDUNG KECAMATAN WALENRANG UTARA KABUPATEN LUWU
Get PDFAren (Arenga pinnata) is a type of palm where almost all of its parts can be utilized, starting from the roots, stems, leaves, flowers, and fruit. Based on the growth rate of sugar palm can show the pattern of distribution using the Morisita index formula. The distribution pattern is a series that has settled on a symptom itself between individuals, which can be divided into three, namely uniform (regular), random (random), and clustered (clustered). This study aims to determine the distribution pattern of the sugar palm (Arenga pinnata) population based on the growth rate. This research was carried out in Sangtandung Village in July 2021. The data collection method used a purposive sampling technique by placing plots in an area with a sugar palm population following the river body 200 meters long. The distribution pattern of sugar palm based on the growth rate was analyzed using the Morisita index formula. Based on the Morishita index, the study results obtained a pattern of palm sugar distribution based on the growth rate, namely seedlings, saplings, trees with clustered patterns, and poles with uniform patterns
PERBANDINGAN STRUKTUR POPULASI TIGA JENIS KELOMPOK MERANTI (Vatica flovirens, Vatica rassak dan Hopea celebica) di KAWASAN HUTAN FARUHUMPENAI DAN DANAU MATANO
No full textPerambahan dan pembakaran sebagai salah satu praktek pembukaan lahan untuk pertanian intensive yang marak dilakukan adalah perkebunan merica. Hal ini menyebabkan keberadaan populasi jenis endemik Hopea spp. dan Vatica spp. menjadi terancam di habitat alaminya. Tujuan dari kajian ini adalah mengetahui Struktur Populasi dari jenis Rode (Vatica flavovirens), Dama’ dere (Vatica rassak) dan Mata Kucing (Hopea celebica) pada habitat alaminya di Kawasa Hutan Faruhumpenai. Hasil penelitian ini menunjukkan jumlah populasi terbesar adalah pada tingkat semai untuk jenis Vatica flavovirens pada blok I, II dan IV. Kerapatan dan jumlah individu terbanyak yaitu berada pada blok I dengan total kerapatan sebesar 1.910 individu/Ha (535 invidu). Pada blok II, kerapatan semai sebesar 382,14 individu/Ha (107 individu), sedangkan pada blok IV terjadi penurunan yang sangat signifikan, kerapatan hanya 62,5 individu/Ha (5 individu). Hal ini menunjukan bahwa terjadi gangguan pada habitat alaminya, dimana terjadi perambahan dan kebakaran yang menyebabkan banyak semai atau anakan mati seketika. Oleh karena itu, perlu upaya perlindungan dan pelestarian dua jenis kayu endemik secara partisipatif melibatkan dan bekerjasama dengan multistakeholder utamanya masyarakat desa. yang berada di sekitar Kawasan Hutan Faruhumpenai.

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
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
