Misi topi bulat: menggapai impian, sejuta harapan / Sarini Ahmad Wakid
No full textLangkah untuk memulakan perjalanan PhD ini bermula sebelum saya memulakan tugas di UiTM. Ketika itu saya masih bertugas di sebuah universiti awam sebagai pengajar sementara. Oleh kerana beberapa kekangan, ianya tertangguh walaupun saya telah mendapat tempat dan biasiswa. Saya meneruskan karier dengan berkhidmat di sebuah institusi pengajian tinggi swasta sebelum saya menyertai barisan tenaga pengajar akademik UiTM Kampus Kuala Pilah, Negeri Sembilan. Masa berlalu dengan pantas tanpa sedar, lebih sedekad saya menangguhkan perjalanan PhD ini rupanya! Lantas, saya tidak lagi teragak-agak untuk mengambil peluang dalam permohonan biasiswa bersama beberapa teman rapat. Syukur, akhirnya saya berpeluang untuk melanjutkan pengajian di Fakulti Sains, UPM dengan tajaan oleh Southeast Asean Regional Center for Graduate Study and Research in Agriculture (SEARCA) dan UiTM. Saya mendapat bimbingan dan dorongan dari penyelia dari UPM (Prof. Madya Dr Nor Azwady Abd Aziz) dan UM (Prof Madya Dr Zazali Alias) yang bersama sejak dari awal penyediaan kertas cadangan sehingga pelaksanaan projek penyelidikan
Soil-transmitted Helminth (STH) Infections in Northern Nigeria between 2000-2022: A Review
No full textSoil-transmitted helminth (STH) infections, caused by parasitic nematodes, are significant public health concern in many parts of the world, including Nigeria. This review aims to comprehensively analyze the available studies and research trends on STH infections among children aged 0 – 17 years in northern Nigeria. The review focuses studies on the prevalence and risk factors related to STH infections from year 2000 – 2022 in this specific region and emphasizes the urgent need for effective control measure to mitigate the burden of these infections. The population involved 25 studies (92.6%) on School-aged Children (SAC) and 2 studies (7.4%) on Pre-school age Children (PSAC). A total of 8 514 children examined, 4 384 (51.5%) males and 4 130 (48.5%) females. Children from rural areas were 5 165 (60.7%) and 3 349 (39.3%) children from urban areas. Sample size ranges from 100 – 620, 22 (74.1%) studies employed Formol-ether concentration as stool examination technique, 4 (14.8%) and 3 (11.1%) used Kato-Katz and Direct smear methods respectively. The overall pool prevalence estimates (PPE) for STH infections were 3 160 (37.1%, 95% CI: 36.5–37.7). PPE for males 1 880 (59.5%, 95% CI: 58.6–60.1) was higher than for females 1 280 (40.5%, 95% CI: 54.2–55.3). Children from rural areas had the highest PPE 1 955 (37.9%) OR 1.26 (95% CI: 0.32–3.73) p=0.02, while children from urban areas had 3 160 (35.9%) OR 1.15 (95% CI: 0.62–5.02) p=0.01. There was no significant association between STH infections and community settings among SAC and PSAC. The most common PPEs by species identified was Ascaris lumbricoides 1 022 (32.3%, 95% CI: 31.7–32.9), hookworm 931 (29.5%, 95% CI: 28.9 – 30.1) and the least; Trichuris trichjura 356 (11.3%, 95% CI: 10.7 – 11.9). Children between 10 – 15 years had highest prevalence (48.6%), and 0 – 9 years had the least prevalence (23.5%) by age groups. Four common risk factors identified, walking barefooted 6 (22.2%) OR 1.16 (95% CI: 1.53 - 6.42) p-0.44, drinking untreated water 12 (44.4%) OR 1.66 (95% CI: 1.30 - 19.49) p=0.53, open field or bush defecation 8 (29.6) OR 3.41 (95% CI: 1.94 - 9.32) p=0.72 and eating unwashed fruits or vegetable 1 (3.7) OR 2.01 (95% CI: 1.32 - 4.51) p=0.54. The research underscores the need for enhanced surveillance, improved sanitation, and comprehensive sustainable interventions to reduce the prevalence and morbidity associated with STH infections in northern Nigeria
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
