A whole-farm study of draught animal power systems in West Java, Indonesia
Draught animals continue to be used widely for land preparation in Indonesian smallholder agriculture despite the adoption of tractors in some other Southeast Asian countries. This implies that rearing and utilisation of draught animals can provide significant economic benefits to Indonesian farmers. This study attempts to define, explore and quantify these benefits and examine the outcome of selected changes to current animal management.
Cattle and buffalo are the main providers of draught animal power. Most are raised on smallholder farms where they must compete with other enterprises for use of the farm's resources. They also generate income through producing outputs which are not draught-related. These factors made it necessary to look at draught-capable animals within the operation of the whole farm system, rather than assessing only their contribution to land preparation.
A monitoring study was conducted over 14 months in Subang. West Java, Indonesia, with eighty respondent farmers.
Data was collected on all inputs to and outputs from the respondent's farm, plus utilisation of the family's labour outside the farm. Linear programming was used to develop models representative of the Subang area based on data from the monitoring study.
Three scenarios were simulated. Firstly, a manual labour farm with no utilisation of draught animals; secondly, the same farm but allowing for the hiring-in of draught animals to prepare land for irrigated rice production; thirdly, both rearing and utilisation of draught animals on the model farm. Two additional scenarios looked at the income effects of reducing labour requirements for cut-and-carry feeding and increasing calf output.
The lowest Total Gross Margin of Rp2.4 million was recorded on the manual labour farm. A very small increase in TGM followed the hiring-in of draught animals; a larger increase in TGM resulted from rearing draught-capable animals on the farm. Reducing labour for animal feeding had little effect on TGM; increasing calf output had a greater income effect.
The models indicate that most of the income benefits associated with cattle or buffalo enterprises derive from non-draught functions, with limited scope for obtaining increased income through changes to draught practices. This implies that the mode] simulated smallholders farm conditions with reasonable accuracy, as almost 90 per cent of farmers in the study area chose not to rear cattle or buffalo but most do rent-in draught animal power from the 10 per cent that rear large ruminants. The umbrella hypothesis of the study-that farmers are generally efficient in the allocation of their resources-remains to be disproved. In terms of future research, priority should be placed on reproductive strategies including a reduction in the calving interval and accelerated early calf growth. Both offer opportunities for obtaining substantial increases in net revenue, as the current levels of productivity achieved in the study area fall well short of management standards commonly achieved in other farming systems
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Pengembangan Pola Integrasi Tanaman-Ternak Merupakan Bagian Upaya Mendukung Usaha Pembibitan Sapi Potong Dalam Negeri
EnglishThe beef self-sufficiency program is aimed at raising beef cattle population to meet national meat consumption. If the program is successful it will reduce imports of live cattle, feeder cattle and beef. Sustainability of this program is expected to achieve beef self-sufficiency in the future. Self-sufficiency is ability to meet domestic demand with beef import of not more than 10 percent which is not produced domestically. Business of beef cattle breeding today is mostly conducted by small-scale farmers with cow-calf operation pattern usually integrated with other agricultural commodity farms. To increase supply of of feeder cattle and population of beef cattle population at national level it requires certain efforts. In order to enhance cattle breeding business from small-scale to medium-scale ones, some efforts are needed such as integration pattern between crops and cattle. Opportunities for integrating crops and beef cattle are promising. The farmers need to apply technologies to access cheaper feed. Credit provision with low interest rate and less complicated procedure to the bank for animal procurement will help farmers in increasing their livestock farm scales. Assistance of extension workers and related livestock officers are critically important to farmers in dealing with their beef cattle breeding business. IndonesianProgram swasembada daging sapi (PSDS) pada dasarnya merupakan kegiatan yang diarahkan untuk meningkatkan populasi sapi potong. Program tersebut diarahkan agar kebutuhan konsumsi daging secara nasional dapat terpenuhi. Keberhasilan program tersebut berimplikasi pada menurunnya prosentase impor baik sapi hidup terutama sapi bakalan maupun daging sapi. Kekurangan daging sapi secara nasional selama ini masih ditanggulangi melalui impor daging maupun sapi hidup yang nilainya cukup besar. Keberlanjutan program ini dimaksudkan agar dimasa mendatang secara perlahan diharapkan Indonesia dapat mencapai swasembada. Pengertian swasembada yang dimaksud adalah besarnya kebutuhan daging asal impor tidak lebih dari 10 persen. Besaran daging impor 10 persen tersebut merupakan daging yang memang belum dapat diproduksi di dalam negeri. Dilihat dari pelaku usaha pembibitan sapi potong saat ini, sebagian besar diusahakan dan dikembangkan oleh usaha peternakan rakyat dengan pola produksi induk-anak (cow-calf operation) dalam usaha skala kecil dan biasanya terintegrasi dengan usaha pertanian lainnya. Untuk meningkatkan ketersediaan jumlah bibit sapi bakalan secara nasional dan dalam upaya peningkatan populasi sapi potong diperlukan upaya–upaya tertentu. Agar usaha pembibitan ternak sapi potong dapat berkembang dari skala kecil menjadi skala menengah salah satu upaya adalah peningkatan skala usaha yang dapat diimplementasikan melalui pola integrasi antara tanaman dengan ternak sapi potong. Peluang untuk pengembangan kearah tersebut sebenarnya terbuka lebar, hanya saja diperlukan upaya serius untuk menindaklanjuti usaha tersebut. Untuk mengarah dari usaha pembibitan tradisional skala kecil ke usaha pembibitan skala menengah memang tidak mudah, banyak hal yang harus diupayakan dan diperlukan penanganan yang lebih serius oleh pemerintah terutama dalam hal peningkatan aplikasi teknologi ke peternak terutama teknologi pengadaan pakan murah dan mudah yang bisa dijangkau oleh peternak. Selain itu kebijakan penyediaan plafon kredit untuk pengadaan ternak dengan bunga rendah yang mudah diakses dengan aturan yang lebih fleksibel sangat membantu peternak dalam meningkatkan skala usaha pembibitan ternak sapi potong. Untuk semua itu, peran penyuluh maupun dinas peternakan dalam membantu peternak untuk mengatasi permasalahan dilapangan sangat dibutuhkan
Variations on the Author
“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
We 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
We 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
We 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
