Nueva España aportó la mayor parte de los recursos que sostuvieron a las fuerzas armadas españolas durante la guerra contra Gran Bretaña que se desarrolló en el Caribe entre 1779 y 1783. En el artículo se analizan las medidas a las que recurrieron las autoridades reales para obtener recursos extraordinarios del Consulado y varios mercaderes de la ciudad de México. Asimismo se exponen algunas de las contraprestaciones que negociaron a cambio de dichos servicios financieros y se plantean diversas hipótesis acerca de los motivos económicos, sociales y políticos que los llevaron a colaborar con el monarca, teniendo en cuenta los negocios que realizaban durante el conflicto bélico y la forma en que eran afectados por la reciente apertura comercial.

Le sujet de cette recherche concerne l'évaluation de l'influence d'une approche pédagogique adaptée tenant compte des dimensions affective et cognitive de la clientèle d'une classe de maturation. Cette approche dite "adaptée" utilise le livre, le conte et les habiletés du conteur dans le but de développer une propension à la lecture chez ces élèves. À la lumière des ouvrages des auteurs tels que Jackson, Hayden, Bettelheim, Jean, Held, Michel et Seung sur l'influence affective et cognitive du livre, du conte et des habiletés du conteur chez l'individu ainsi qu'à la lumière du modèle théorique de la compréhension du rôle de l'affectivité relié au processus de la lecture de Mathewson, nous avons formulé l'hypothèse que l'application de l'approche pédagogique adaptée axée sur le conte et les habiletés du conteur augmente la propension à la lecture chez les élèves d'une classe de maturation. La cueillette des données a été réalisée à l'aide de l'évaluation d'un expert (avant et après l'application de l'approche pédagogique adaptée), d'un questionnaire adressé aux sujets, d'un questionnaire adressé aux parents (avant et après l'application de l'approche pédagogique adaptée) et des observations de l'enseignante. L'analyse de l'ensemble des résultats et des observations durant la période de l'expérimentation confirment l'hypothèse de cette recherche.

In the study, the production efficiency of catfish in Cross River State was determined. Data was obtained from 120 fish farmers were randomly selected from Cross River Agricultural Zones, using a multistage random sampling technique. Multiple regression analysis model was the main tool of data analysis where different functions were tried. The results indicated that Cobb-Douglass production function had the best fit in explaining the relationship between output of catfish and inputs used, the coefficient of multiple determinant (R2 = 0.61) indicates that sixtyone percent of the variability in output of catfish is explained by the independent variables. The results also indicate that farmers’ educational level positively influence their level of efficiency in catfish production in the study area. The F-value of 16.427 indicates the overall significance of the model at 1 percent level, indicating that there is a significant linear relationship between the independent variables taken together and the yield of catfish produced in Cross River State. The marginal value products of fish pond size (farm size), labour and feed (diet) were N67.50, N 178.13 and N 728.00 respectively, while allocative efficiency for (farm size), labour and feed (diet) were (0.09 over utilized, 2.85 under utilized and 0.99 over utilized), respectively, there existed allocative in-efficiency, there is a high potential for catfish farmers to increase their yields and income. Based on the findings of this study, it is recommended that fish farmers should expand fish farms, improving on production efficiency and adopting new technologies. Regular awareness campaign about new technologies in fish farming should be embarked by extension agents to make fish farmers know the importance of adopting new technologies.

Environmental changes are some of the factors that affect fisheries and biological characteristics of fishes. The African catfish Clarias gariepinus (Burchell, 1822) has biological characteristics that enable it to persist under various stressful environmental conditions. However, few studies have examined how the African catfish responds to conditions created by a changing climate. The study examined some of the fishery and biological characteristics of African catfish in Lake Wamala (Uganda) to provide an understanding of their response to changing climatic conditions using data for the period 1950 - 2013. Temperature around the lake increased by 0.02ºC/year since 1980, commensurate with the regional trend, while rainfall was above average since 1996, except in 2004 and 2008. Lake depth was strongly positively correlated with rainfall (r =0.83, n= 6, p<0.05) up to 2000, after which, lake depth decreased amidst increase in rainfall. The contribution of African catfish increased from 20% to 85% and 17% to 78% respectively to commercial and experimental catches respectively between 1975 and 2013 despite the decrease in lake depth. The modal total length, condition factor, food, and fecundity did not change. Only size at first maturity decreased from 37.5 to 30 cm TL in females and 39.5 to 34.2 cm TL in males between 1999/2000 and 2012/2013. The biological characteristics of the African catfish were comparable with those of the same species in other lakes and remained relatively stable. The results suggested that the African catfish has the capacity to persist and/or adjust appropriately under conditions created by climate variability and change, and if properly managed, can sustain the fisheries of Lake Wamala.
