    Abstract.The author has shown that modern technologies do not always meet the expectations of farmers, and this may adversely affect the pace of innovation. It has been confirmed that the developers of agricultural equipment do not clearly understand the context of the use of products and identified the need to use a multi-factor approach: therefore, partners possessing specific knowledge in different areas should join efforts in project activities at all stages of innovation. (Research purpose) To prove that a user-centered design and a multi-factor approach in the development of agricultural machinery increase their efficiency and accelerate the introduction of innovations. (Materials and methods) It is shown that Finnish research and development projects of agricultural machinery design involve numerous participants and end users. For example, the seven-metre-wide combi drill ‘Junkkari W700’ was designed by the Finnish manufacturer Junkkari Oy in close cooperation with end-users and researchers. As a result of the innovation process several benefits have been realized. The drill is easy to operate and service. The users appreciate the straight-forward construction and moderate cost of the drill as compared to competing pneumatic drills. The need for hydraulics is minimized and the row spacing and coulter design has been optimized so that economical tractors with moderate drawbar power can be used. The ISOBUS-based control electronics was designed to be fitted either in the existing tractor or, if ISOBUS is missing, with an optional cable-set and terminal. That enables the users to easily integrate the drill in existing machine chains, having either modern or older tractors, without extra tractor investments. Much attention was put on quality, e.g. individual feeders for every coulter give accurate dosage of seed and fertilizer. The prototyping together with end-users and researchers enabled Junkkari to speed up the innovation process. (Results and discussion) Several benefits proved to have been realized. First of all, the drill is easy to operate and service. The users appreciate the straight-forward construction and moderate cost of the drill as compared to competing pneumatic drills. The need for hydraulics is minimized and the row spacing and coulter design has been optimized so that economical tractors with moderate drawbar power can be used. The ISOBUS-based control electronics as well as an optional cable-set and terminal were designed to be fitted either in the existing tractor. That enables the users to easily integrate the drill in existing machine types, having either modern or older tractors, without extra tractor investments. The design quality was approved, e.g. individual feeders for every coulter give accurate metering of seeds and fertilizers. (Conclusions) The author proves that user-centered design and multi-factor approach methodologies have benefits both for the users and manufacturers. Swift innovation process saves resources and minimizes the need for excess iterations in the innovation process

    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

    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

    Get PDF
    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

    Get PDF
    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

Показали, что современные технологии не всегда соответствуют ожиданиям фермеров, а это отрицательно сказывается не темпах внедрения инноваций. Подтвердили, что разработчики сельхозтехники недостаточно четко понимают контекст использования продуктов. Выявили необходимость использования многофакторного подхода: партнерам, обладающим специальными знаниями в разных областях, следует объединять усилия в проектной деятельности на всех этапах внедрения инноваций. (Цель исследования) Доказать, что ориентированная на пользователя конструкция и многофакторный подход при разработке сельскохозяйственных машин повышают их эффективность и ускоряют внедрение инноваций. (Материалы и методы) Показали, что в финских исследованиях и разработках конструкции сельскохозяйственных машин в процесс были включены многочисленные участники и конечные пользователи. Например, комбинированную сеялку Junkkari W700 с шириной захвата 7 метров финский производитель Junkkari разработал в тесном сотрудничестве инженеров и фермеров. (Результаты и осуждение) Подтвердили, что такой подход помогает реализовать несколько преимуществ, прежде всего простоту и удобство в эксплуатации и обслуживании сеялки, а также умеренную стоимость по сравнению с пневматическими аналога-ми. Потребность в гидравлике сведена к минимуму, а междурядное расстояние и конструкция сошников оптимизированы, что позволяет использовать экономичные тракторы с умеренной тягой. При агрегатировании с трак-торами предусмотрены как система ISOBUS, так и дополнительный комплект кабелей и выводов. Установили, что фермеры могут легко интегрировать сеялку в существующие типы машин, используя современные или старые тракторы, без дополнительных затрат на новые тракторы. Подтвердили качество конструкции, например, индивидуальные дозаторы для каждого сошника обеспечивают точную дозировку семян и удобрений. (Выводы) Доказали, что ориентированная на пользователя конструкция и многофакторный подход имеют преимущества как для фермеров, так и для машиностроителей. Определили, что сокращение количества этапов внедрения инноваций ускорит инновационный процесс и сэкономит ресурсы

    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
