Combined Effects of Allelochemical and Pesticide Treatment on the Growth of Cucumber Plants

Allelochemicals are biochemicals produced by one plant that inhibits the success of other plants in its vicinity. These allelochemicals are sometimes produced naturally or as a result of stimulus or stress. Ferulic acid is a widespread allelochemical found in cucumbers (Cucumis sativus). Artificial inhibitory chemicals such as the pesticide zeta cypermethrin may create new interactions with ferulic acid. We found that cucumbers acclimate to ferulic acid over time while the inhibitory effects of pesticide remained relatively constant over 14 days

Phylogenetic analyses of rotavirus a from cattle in uruguay reveal the circulation of common and uncommon genotypes and suggest interspecies transmission

Uruguay is one of the main exporters of beef and dairy products, and cattle production is one of the main economic sectors in this country. Rotavirus A (RVA) is the main pathogen associated with neonatal calf diarrhea (NCD), a syndrome that leads to significant economic losses to the livestock industry. The aims of this study are to determine the frequency of RVA infections, and to analyze the genetic diversity of RVA strains in calves in Uruguay. A total of 833 samples from dairy and beef calves were analyzed through RT-qPCR and sequencing. RVA was detected in 57.0% of the samples. The frequency of detection was significantly higher in dairy (59.5%) than beef (28.4%) calves (p < 0.001), while it did not differ significantly among calves born in herds that were vaccinated (64.0%) or not vaccinated (66.7%) against NCD. The frequency of RVA detection and the viral load were significantly higher in samples from diarrheic (72.1%, 7.99 log10 genome copies/mL of feces) than non-diarrheic (59.9%, 7.35 log10 genome copies/mL of feces) calves (p < 0.005 and p = 0.007, respectively). The observed G-types (VP7) were G6 (77.6%), G10 (20.7%), and G24 (1.7%), while the P-types were P[5] (28.4%), P[11] (70.7%), and P[33] (0.9%). The G-type and P-type combinations were G6P[11] (40.4%), G6P[5] (38.6%), G10P[11] (19.3%), and the uncommon genotype G24P[33] (1.8%). VP6 and NSP1-5 genotyping were performed to better characterize some strains. The phylogenetic analyses suggested interspecies transmission, including transmission between animals and humans.Fil: Castells, Matías.

A cointegration analysis of the okun law in Colombia : An approach using non-linear smooth transition autoregressive models

37 páginasThe intended research estimated the Okun’s relationship for Colombia with a STAR procedure, in which the variable capable of enabling the transition was the long-run disequilibrium term. The study postulates two different regimes that characterize Colombian economy with the nonlinearity approach of the Okun’s Law: A High regime and a Low regime. The periods in which each state of nature took place where determined and the economic conjuncture that lead to them was explored. The results suggested an improvement of the non- linear analysis of Okun’s Law, as well as that employment indeed is linked with economic growth. This could contribute the construction of a correct design, implementation and effectiveness of future policies in the country.Economía y Finanzas InternacionalesEconomista con énfasis en Finanzas Internacionale

Erratum: Education hubs and private higher education expansion in small island developing states contexts : the case of Mauritius

Background: This article is located in the context of governments of small island developing states supporting education hubs in collaboration with local and global partners. Whilst current literature on the development of education hubs focuses on the macro policy perspectives looking at how education hub policies are designed and enacted upon at national level, there are relatively few studies on the micro perspective of the institutions. Aim: By comparing the agendas, experiences, potential and drawbacks of these institutions, the article explores the sustainability prospects of these variants of education hubs. Methods: We selected three case studies: a public distance education university, a local private university and an international branch university within the same broader environmental context to examine how a ‘vision of possibilities’ is played out within three different institutional agendas. Results: The case studies reveal that marketisation and privatisation marginalise the pursuit of quality which recedes in preference for securing international economic resources to activate the local developmental agendas and how the exercise privileges skewed power relations which maintain centre–periphery hegemonic hierarchies in the cross-border collaborations. Conclusion: The uptake of an education hub as a national target exemplifies how the uncritical and indiscriminate borrowing of policies normalises and is reframed to appear as ‘moments of equity’. But in reality it promotes individual competitiveness at the expense of the common good
