The Effect of Inventory Management Practices on Supply Chain Performance of Perishable Food Products: A Case of Small Enterprises in Dar es Salaam
Full text linkThis study examines how inventory management practices affect supply chain performance for perishable food products among small enterprises in Dar es Salaam, Tanzania, addressing the challenge of managing perishables efficiently in resource-constrained environments. Perishable goods require precise inventory practices due to their limited product lifespan and high risk of spoilage. The study focused on inventory turnover, inventory record accuracy, and demand forecast accuracy as key variables influencing supply chain performance. A quantitative research design was employed, with data collected from 292 respondents using structured questionnaires targeting managers and staff involved in inventory and supply chain operations. Descriptive statistics and multiple regression analysis were used to interpret the data. The results revealed that all three inventory practices had a statistically significant positive impact on supply chain performance, with inventory turnover exerting the greatest influence. Accurate inventory records and reliable demand forecasts were also found to be essential for improving order fulfillment and minimizing waste. The study concludes that improving inventory practices can significantly enhance the performance of perishable supply chains in small enterprises. It recommends adopting simple tracking tools, coordinated ordering strategies, and basic forecasting methods, along with staff training, to strengthen operational capacity in informal urban markets
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
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
The The Effects of Digital Technologies on Green Logistics Performance in Tanzania: A Moderation and Mediation Analysis Using PLS-SEM
No full textThe aim of this study was to assess the impact of digital technologies on the green logistics performance of Tanzanian procuring entities. The study was guided by the technology-organization-environment model, the Schumpeter theory of innovation, and the Unified Theory of Acceptance and Use of Technology. A total of 427 respondents were included in the study, and data were collected using the stratified sampling technique. The study employed post positivism research paradigm and involved the use of explanatory cross-sectional surveys in data collection. The data were collected by administering questionnaires and examining relevant documents. The inferential statistics analysis of data collected was conducted using Partial Least Squares Structural Equation Modeling with the help of SmartPLS 4 software. The data collected on respondents' profiles was analyzed using descriptive statistics with the assistance of IBM SPSS Statistics Version 26. The results suggest that the use of augmented reality, predictive analytics, information and communication technology (ICT) specialists, and the intention to use robots all have a beneficial impact on the efficiency and effectiveness of green logistics. The study recommends that suppliers and buyers in Tanzania and other developing countries should use robots, augmented reality, ICT specialists and predictive analytics to improve the green logistics performance
