ABSTRAK
Dalam tugas akhir ini bertujuan untuk mendapatkan kendali optimal prey pada sistem predator
prey dengan fungsi respon holling tipe IV dan pemberian makanan alternatif terhadap predator.
Kendali optimal didapat dengan menggunakan prinsip maksimum pountryagin. Berdasarkan dari
persamaan diferensial dinamik prey dan fungsi tujuan dibentuk persamaan hamilton, state, costate,
dan stasioner. Selanjutnya disimulasikan menggunakan metode sweep maju-mundur. Hasil dari
simulasi numerik yang diperoleh menujukkan bahwa ketika semakin besar koefisien konsumsi
predator terhadap prey dan koefisien upaya pemanenan prey maka semakin rendah pertumbuhan
populasi prey. Semakin besar koefisien laju pertumbuhan intrinsik prey dan pemberian makanan
alternatif pada predator maka semakin tinggi pula pertumbuhan populasi prey.
Kata kunci: Holling tipe IV, Kendali optimal, Prinsip maksimum poutryagi

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

ABSTRACT
SAPARUDDIN. 2014. The Influence of Problem Based Learning Model by Employing Mind Mapping Technique Towards Critical Thinking Ability and Students’ Result in Learning Biology Subject (Supervised by Jasruddin and Muhammad Wiharto)
The study aimed at examining (i) the influence of problem based learning model byu employing mind mapping techniques towards critical thinking ability of students; (ii) the influence of problem based learning model by employing mind mapping towards students’ result in learning Biology subject; (iii) the correlation between students critical thinking ability and students’ result in learning Biology subject. The study was pre- experimental design with One Group Pretest-Posttest design. The sample of the study was one class of grade XI IPA 9 at SMAN 1 Sungguminasa of academic year 2013/2014 as 50 students. Sample was taken by employing random sampling technique. The instruments of the study were test of critical thinking ability to measure critical thingking ability and test of learning result to measure students’ result in learning Biology on the excretory system in a form of multiple choice. Data were analyzed by employing statistic descriptive and inferential test ( paired samples) and product moment correlation. The descriptive analysis revealed that there was improvement from pretest to posttest for critical thingkling ability and students’ result in learning biology. The mean of pretest for critical thingking ability was 24.10 and 79 for posttest; whereas, the mean of pretest for students’ learning result was 29.80 and 77.28 for posttest. The result of inferential analysis indicated that (i) The first hypothesis showed that tcount 40.853>ttable 1.68, H0 was rejected, meaning that there was influence of problem based learning model by employing mind mapping technique toward critical thingking ability students; (ii) The second hypothesis showed that tcount 46.682>ttable 1.68, H0 was rejected, meaning that there was influence of problem based learning model by employing mind mapping technique toward students’ learning result; (iii) The thirdth hypothesis showed that there was significant positive correlation between critical thingking ability and students’ result in learning Biology with correelation value 0,765.
Keywords: problem based learning model, mind mapping technique, critical thinking ability, and students’ result in learning Biology
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
