Role of CRISPR-Cas9 in agricultural science
No full textClustered regularly interspaced short palindromic repeat (CRISPR), a potent gene-editing tool was found in 2012. CRISPR is a genetic engineering technique that enables genome editing in living creatures and is based on the bacterial CRISPR-Cas9 antiviral defense mechanism. It is simpler, less expensive, and more accurate than previous gene editing techniques. It also has a wide range of valuable uses, including improving crops and treating genetic diseases. Plant science has benefited more from the CRISPR/Cas9 editing technique than medical science. CRISPR/Cas9 has been used in a range of crop-related research and development domains, including disease resistance, plant development, abiotic tolerance, morphological development, secondary metabolism, and fiber creation, as a well-developed cutting-edge biotechnology technique. This paper summarized the role of the CRISPR-CAS9 tool in modern agricultural science
Progress and Potential Drawbacks of Modern Agricultural Technologies: A Literature Review
Full text linkThe production of agriculture has undergone new modifications as a result of agricultural technologies. These not only boost agricultural output but may also significantly raise the caliber of produced food, cut labor expenses, boost farmers' incomes, and achieve agricultural modernization. The use of precision agriculture (PA) is expanding due to the rapid socioeconomic changes that are occurring in certain developing nations. There are enormous ramifications for urbanization, energy consumption, and economic growth in certain developing nations when fundamental changes occur. The research status and current agricultural technology achievements are carefully summarized in this study. In-depth discussions of thirteen significant agricultural technologies are provided in this article. All significant technologies from developed countries are discussed so that under-developed and lower-developed countries will benefit from this paper. Finally, some fresh concepts for each technology are offered, and potential issues in establishing such sophisticated technologies are identified. The main objective of this review is to increase knowledge of modern agriculture and the development process in the agricultural field
Ecological Advancements and Developments of Agroforestry
Full text linkAgroforestry is a conventional method of land use that could help to address agricultural environmental issues. In order to take advantage of the ensuing ecological and economic interactions, agroforestry is the technique of consciously integrating woody vegetation (trees or shrubs) with crop and/or animal systems. According to recent studies, the global agri-food industry may reach more sustainable methods of producing food and fiber by adopting agroforestry techniques and principles more widely. This would benefit farmers economically and would benefit society as a whole in terms of the environment. Agroforestry promotes eco-intensification based on resource efficiency and offers a wide range of provisioning, regulating, cultural, supporting ecosystem services, and environmental advantages. In this review, we discussed agroforestry with its advantages and developments
Challenges, Developments, and Perspectives of Conservation Agriculture (CA) in Modern Agricultural System
No full textOne of the long-term solutions for agriculture’s depletion of natural resources and degradation of the environment has been identified as conservation agriculture systems with proper crop and soil management. With the progress of the era, great changes have taken place in the field of agriculture. At present, it is possible to produce sufficient crops through conservation agriculture, along with economic, agronomic, and environmental benefits. Conservation techniques greatly lower the danger to food safety on a farm. CA is a farming method used to boost crop yield and sustainability that depends on three principles: minimal soil disturbance, crop rotation, and surface crop residue retention. This paper summarizes the importance, benefits, and challenges of conservation agriculture in a precise manner. In this study, we also discuss the way to increase the practice of conservation agricultureas well as the present research scenario of Bangladesh. At last, some research gaps are highlighted. Through this review, students and researchers will know the current development status of CA clearly and briefly
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
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
