Revealed comparative advantage and competitiveness of Mexican mango exports
Get PDFIn 2020, Mexico positioned itself as the fourth producer and the main exporter of mango, supplying around 18.44% of the world market and 88.28% of the US market, being the main importer. An analysis of the competitiveness of the Mexican mango in the world market was carried out from 1994 to 2020, by calculating the index of revealed comparative advantage (IVCR) and normalized revealed comparative advantage (IVCRN), with the purpose of knowing the export specialization of Mexico and thus be able to determine the presence of comparative advantages in exports. The average values obtained for the US market were 1.09 (IVCR) and 0.04 (IVCRN), for the Canadian market it was 6.33 (IVCR) and 0.69 (IVCRN), reflecting that the Mexican mango export sector is competitive and has comparative advantages. because the indices are positive.
Keywords: comparative advantage, competitiveness indices, production, market.Objective: The analysis of competitiveness of Mexican mango in the global market from 1994 to 2020 was conducted.
Design/methodology/approach: The revealed comparative advantage index (RCAI) and the normalized revealed comparative advantage index (NRCAI) were calculated, with the aim of understanding the exporting specialization of Mexico and thus determine the presence of comparative advantages in exports.
Results: The average values obtained for the USA market were 1.09 (RCAI) and 0.04 (NRCAI), and for the Canadian market 6.33 (RCAI) and 0.69 (NRCAI).
Conclusion: The export sector of Mexican mango is competitive and has comparative advantages because the indices are positive
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
Availability, accessibility, and intake of vegetables native to Mexico
Get PDFObjective: to analyze the intake of vegetables native to Mexico from 1980 to 2020, based on the food security approach. Methodology: the availability and accessibility dimensions of food security were taken into consideration for this study; in addition, descriptive statistics and regression models were used. Results: the apparent national intake of native vegetables increased during the study period, reaching 6.821 million tons in the year 2020, while the per capita intake was 148 grams in the same year. The actual income and the quarterly family expenses on vegetables, pulses, and seeds decreased from 1,082 Mexican pesos in 2020. Study Limitations/Implications: the food utilization and stability dimensions that encompass food safety were not included in the study. Conclusions: public food security policies must promote the production and intake of vegetables native to Mexico and increase the actual income of the most vulnerable Mexican families, facilitating accessibility to these products
Evaluación de rentabilidad financiera en la producción de Bursera glabrifolia (Kunth) Engl en condiciones de vivero
Get PDFObjective: Determine the financial profitability of the production of Bursera glabrifolia (Kunth) Engl in nursery conditions, to carry out forest plantations that allow the regeneration of this type of vegetation, the recovery of soils and to generate the raw material of the alebrijes.Design/methodology/approach: Financial information was collected for the production of B. glabrifolia plant, prices and quantities of inputs were obtained, as well as infrastructure to calculate financial indicators and to determine the profitability of the project, the project evaluation methodology was used to calculate the profitability of the project. investment in terms of net present value (NPV), internal rate of return (IRR) and minimum acceptable return rate (MARR); the financial analysis was carried out for 10 years.Results: The results obtained are an initial investment in mexican pesos: 850,000.00 and the financial indicators obtained were: NPV$22,440.5 IRR9% and cost benefit ratio1.Limitations on study/implications: This project is the beginning of the productive chain of the alebrijes and promotes a sustainable forest management through the commercial plantations of B. glabrifolia.Findings/conclusions: The project is viable considering that it has a low IRR because it is a social and ecological program to help the Valles Centrales region of Oaxaca, Mexico, recover its endemic vegetation and at the same time promote the generation of plantations of Bursera glabrifolia in the villages whose main activity is the production of alebrijes
Availability, accessibility, and intake of vegetables native to Mexico
Get PDFObjective: The objective of the research was to analyze the consumption of native vegetables in Mexico through the food security approach for the period 1980-2020. Methodology: To carry out the study, the dimensions of availability and access covering food security were taken into consideration, also descriptive statistics and regression models were used. Results: The apparent national consumption of native vegetables grew up in the study period, it was 6 million 821 thousand tons in the year 2020, and per capita consumption was of 148 grams. The real income and quarterly expenditure of families for vegetables, legumes and seeds had a decreasing trend, the latter was 1,890 pesos in 1980 and 1,082 pesos in they year 2020. Limitations on study/implications: It was missing to include the dimensions of biological utilization and stability that encompasses food safety. Conclusions: Public food security policies should promote the production and consumption of native vegetables and increase the real income of the most vulnerable Mexican families, and thus facilitate access to these products.Objective: to analyze the intake of vegetables native to Mexico from 1980 to 2020, based on the food security approach.
