FARMERS’ PERCEPTION OF CLIMATE CHANGE AND ADAPTATION IN KHYBER PAKHTUNKHWA PAKISTAN: A CASE STUDY OF NOWSHERA DISTRICT
No full textClimate change has a devastating effect on yields of major crops and is considered to become a threat to national food security. Therefore, this study was designed to explore farmers’ perception of climate change and investigate changes in seasonal temperature and rainfall over the last two decades. Focus Group Discussion (FGD) was employed to analyze the perceptions of farmers about climate change vulnerabilities and their adaptation strategies to cope with the changing climatic conditions. The results revealed that regarding environmental services, water availability was decreased due to low rainfall. In addition, the supply of firewood was also decreased due to a high demand on fuel and construction purposes. Furthermore, there was an increase in population density and a decrease in medicinal plants and wildlife due to deforestation. The temperature increased over the last 20 years and the length of the summer period was longer due to less rainfall while the duration of winter turned to be short. It is reported that the spring season is almost merged in the summer season, with the increase of temperature during the spring. Therefore, agriculture research should develop a variety of crops that can adapt to climatic extremes and educate farmers through seminars and campaigns to build their adaptive capacity dealing with the use of cultural practices to mitigate climate change
ASSESSMENT OF EXTENSION AGENTS’ KNOWLEDGE AND SKILLS REGARDING PEST MANAGEMENT IN KHYBER PAKHTUNKHWA PROVINCE -PAKISTAN
No full textThe research study was initiated in Khyber Pakhtunkhwa province of Pakistan toinvestigate about the extension agents’ knowledge and skills regarding pestmanagement. Key objectives of the study were to know the present levels of theirpotentials and to judge their interested level of skills and potentials in pestmanagement capabilities needed by Agriculture Extension Officers (AEOs) fortheir effective job performance. Respondents were asked to report the selfperceived level of expertise possessed by them and the level required for smoothperformance regarding pest management measures in the field to sustainagriculture. The present and interested levels of potentials were measured both onLikert scale ranging from 1 to 5 such as “very low” as “1” and “very high” as “5”.There were significant differences observed in the agricultural officer’s potentialfor sustaining agriculture regarding age, professional qualification and jobexperience. Age, professional qualification and job experience have significantassociation on technical efficiency regarding protection of plants from pests forsustainable agriculture. Moreover, required level in said capability was higher inidentification of major field crops’ diseases as well as the guidance of farmers forherbicides use against weeds. Trainings of AEOs were required in identification ofdiseases and insect pests of minor crops along with their causes. Hence it isrecommended that AEOs may be trained and well prepared in the mentionedparameters of pest management measures to face challenges in the field ofagriculture and can face farming community effectively to raise their livingstandards by sustaining agriculture for their coming generation
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
