Abstract
The use of pesticides in Indonesia today has reached an alarming level. The use of chemical pesticides is the most widely used means of controlling Plant Pest Organisms (OPT) by farmers in Indonesia, because they are considered effective, easy to use and economically profitable. However, so far, farmers tend to use excessive pesticides, and government policies are not optimal in providing assistance and supervision as well as training to farmers in order to increase farmers' knowledge in the use of pesticides and to carry out supervision and regulations, to supervise pesticide users. The purpose of this study was to identify the behavior of shallot farmers in the use of pesticides in Lembah Gumanti District, Solok Regency and analyze the factors that influence the behavior of shallot farmers in the use of pesticides. This research method uses primary data and secondary data and is supported by using the structural equation modeling (SEM) method. The results showed that the predisposing factor had a significant effect on the behavior of shallot farmers in using pesticides. Enabling factors have a significant effect on the behavior of shallot farmers in the use of pesticides. The reinforcing factor has a significant effect on the behavior of shallot farmers in the use of pesticides. The predisposing factor has a significant effect on the intention of angry shallot farmers in using pesticides. Intention has a significant effect on the behavior of shallot farmers in the use of pesticides. Predisposition has a significant effect on the behavior of shallot farmers in the use of pesticides with the intention of mediating. The conclusion is that shallot farmers understand that the use of insecticides for pests, fungicides for fungi, and herbicides for weeds is to deal with pests and diseases in order to avoid crop failure. Farmers mix pesticides when plants are attacked by various types of pests and diseases, and spray regularly a maximum of 2 times a week. The factors that significantly influence the behavior of shallot farmers in the use of pesticides are: enabling factors which consist of indicators of environmental facilities, training, personal protective equipment, affordability, and socio-economic; reinforcing factor consisting of indicators of social support, legislation and supervision; and the intention factor, which consists of indicators of subjective norms, behavioral control and attitudes. The predisposing factor which consists of indicators of knowledge, attitudes, beliefs, values and motivation has a significant influence on farmer behavior through the intention factor as a mediating variable

Latar Belakang: Tuba Eustachius patulous (TEP) merupakan suatu keadaan dimana saluran tuba Eustachius (TE) terbuka terus menerus. Terdapat beberapa faktor yang diduga menjadi penyebab TEP, salah satunya adalah penurunan bantalan lemak Ostmann’s sekitar TE akibat penurunan berat badan drastis yang dapat terjadi pada pasien karsinoma saluran cerna. Diagnosis TEP ditegakkan berdasarkan anamnesis, pemeriksaan fisik berupa otoskopi serta pemeriksaan penunjang nasoendoskopi, timpanometri dan tes fungsi tuba. Tujuan: Mengetahui hubungan penurunan berat badan dengan TEP pada pasien karsinoma saluran cerna. Metode: Penelitian dilakukan secara analitik dengan metode potong lintang (cross sectional). Sampel penelitian adalah 24 pasien karsinoma saluran cerna yang telah memenuhi kriteria inklusi dan eksklusi. Penurunan berat badan dibagi menjadi 2 kelompok yaitu ≤15 kg dan >15 kg. Semua data penelitian dilakukan uji perbandingan non parametrik Pearson Chi-Square. Hasil: Dari 24 sampel, didapatkan 1 pasien TEP bilateral dan 1 pasien TEP sinistra. Kedua sampel mengalami penurunan berat badan >15 kg. Kesimpulan: Tidak terdapat hubungan penurunan berat badan dengan TEP pada pasien karsinoma saluran cerna secara statistik.

Diagnosis dan Penatalaksanaan Laringomalasia
Get PDFLatar belakang: Laringomalasia (LM) merupakan penyebab tersering stridor inspirasi kongenital pada bayi. Sekitar 80% kasus merupakan derajat ringan dan sedang yang dapat membaik serta resolusi sampai usia 2 tahun sedangkan 20% merupakan derajat berat yang membutuhkan tindakan pembedahan Tujuan: Mengetahui dan memahami etiologi, diagnosis dan penatalaksanaan laringomalasia. Tinjauan Pustaka: Diagnosis laringomalasia dapat ditegakkan dari anamnesis, pemeriksaan fisik serta pemeriksaan penunjang laringoskopi serat optic fleksibel. Etiologi pasti laringomalasia belum diketahui, namun terdapat 3 teori yang diduga berperan yaitu imaturitas kartilago, imaturitas neuromuskular dan abnormalitas anatomi. Terdapat hubungan antara laringomalasia dengan laryngopharyngeal reflux (LPR). Penatalaksanaan konservatif dilakukan pada LM derajat ringan dan sedang sedangkan tindakan pembedahan dilakukan pada derajat berat, laringomalasia dengan komorbid dan laringomalasia yang gagal terapi konservatif. Kesimpulan: Laringomalasia merupakan kolapsnya struktur supraglotis ketika inspirasi yang mengakibatkan adanya stridor inspirasi. Laringomalasia derajat berat dapat mengancam nyawa. Sebagian besar kasus akan resolusi sendiri, namun sekitar 20% memerlukan tindakan pembedahan. Supraglottoplasti merupakan tindakan pembedahan pilihan untuk kasus laringomalasi
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
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
