    Journal ArticleThe consumption of street food is associated with the provision of unhealthy, unsafe, and nutritionally unbalanced meals, presenting a public health concern. This study was designed to assess food safety knowledge, attitude and practices of night street food vendors in Morogoro Municipality. A cross-sectional study involved 256-night street food vendors was performed, using a structured questionnaire. The results reported that most of the vendors were females (77%) and half of the vendors were aged between 20 to 30 years. Majority of vendors ,62.9% had been vending food for 4-5 years. Generally, the study revealed medium attitudes (95.3%) and moderat

    European Journal of Nutrition & Food Safety Volume 15, Issue 10, Page 1-20,Noodles with varying percentages of wheat flour, moringa leaf and Sardine powders were developed and tested for texture, cooking quality, and sensory qualities. Various formulations were used to make the noodle samples. Noodles with moringa leaf powder were developed using in the following wheat and Moringa proportions in percentage: 99.6:0.4 (WM1), 99.2:0.8 (WM2) and 99:1 (WM3). Noodle samples containing sardine powder were created in the following ratios: 95:5 (WS1), 90:10 (WS2), 85:15 (WS3), and 100:0 wheat flour. Textural qualities of the noodle samples were measured, including hardness, cohesiveness, springiness and adhesiveness. The inclusion of moringa leaf powder and sardine powder resulted in a considerable reduction in hardness and cohesiveness when compared to the wheat control. The noodles became softer and less cohesive as the concentration of moringa leaf powder or sardine powder increased. The noodle samples' cooking loss, volume increase and water absorption were also measured. Higher concentrations of moringa leaf powder or sardine powder resulted in greater cooking loss as well as lower volume and water absorption. This implies that the inclusion of these powders altered the texture and water-holding capacity of the noodles. Additionally, sensory evaluations were performed to determine the acceptability of the developed noodles in terms of color, aroma, texture, taste and overall acceptability. The results revealed that when the concentration of moringa leaf powder or sardine powder increased the sensory properties of the noodles samples were altered. Lower concentrations of these powders were related with greater acceptance scores in general. Specific characteristics of the noodles-, such as color, aroma, saltiness and hardness were evaluated using quantitative descriptive analysis. The results showed that adding moringa leaf powder and sardine powders altered these properties with larger concentrations causing more noticeable changes

    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

    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

    No full text
    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
