Costos logísticos y exportación de maíz vía marítima 2008-2016

La investigación ha tenido como objetivo establecer la relación de los costos logísticos y la exportación de maíz por vía marítima en el periodo 2008-2016. La investigación es descriptiva correlacional y de diseño no experimental. Una vez recopilados los datos, se organizaron a través de tablas, se presentaron mediante gráficos de línea, teniendo en cuenta las siguientes dimensiones de costos logísticos (costos de operaciones en muelle, infraestructura portuaria, tiempo del procedimiento de exportación) y de la exportación (volumen, valor y precio de exportación), por último se realizó la explicación de los gráficos, de esa forma se procedió a comparar los indicadores de cada dimensión mostrando una tendencia de disminución durante el periodo 2008 – 2016. En conclusión de acuerdo con los resultados de la investigación realizada ha quedado demostrado que, los costos logísticos en la exportación marítima en el horizonte del tiempo tienden a disminuir básicamente por un mayor empleo de la tecnología, mejores condiciones de embalajes sobre las mercancías, menores costos de servicios conexos derivados de operaciones propia del despacho aduanero orientado básicamente por la sobre oferta de servicio que genera una guerra de precios a favor del exportador

Why academic depth and rigour in university-based coursework matters for prospective teachers

From text: Initial teacher education (ITE) programmes are expected to prepare teachers who have the capacity to develop conceptually strong, responsive and inclusive teaching practices. The extent to which ITE programmes have been successful in this endeavour has been questioned both internationally (e.g. Lancaster & Auhl, 2013) and within the South African context (Council on Higher Education [CHE], 2010). In retrospect, it is not surprising that the review of initial teacher education (ITE) programmes conducted by the CHE between 2005 and 2007 found that the sector was experiencing tension between “the theoretical and conceptual rigour expected of a professional degree and the vocation-specific training of teachers” for classroom readiness (CHE, 2010: 103)

An Investigation of Alternative Factor Models of Impulsivity using the UPPS-P

The UPPS-P measures impulsivity as a five-factor construct (lack of premeditation, lack of perseverance, positive urgency, negative urgency and sensation seeking). Drawing on a number of theoretical considerations and alternative conceptions of impulsivity, the current study used confirmatory factor analysis (N = 1635) and multiple regression to evaluate and test alternative models comprising three, five, and a hierarchical model containing latent factors. The five factor and hierarchical models were shown to be valid and of near identical fit, whereas the three-factor model fit the data poorly. The current findings suggest that both the five factor and hierarchical models are useful applications of the UPPS-P. Depending on the purpose of future research, both models demonstrate utility in both risk assessment and treatment development. Multiple regression analysis revealed that positive urgency predicted problem gambling, which supports the predictive utility of impulsivity as a five-factor construct. While the latent factors of the hierarchical model are consistent with emerging theory, those using the UPPS-P should not overlook the unique contributions of the five factors. As the current study found meaningful predictive distinctions between positive and negative urgency, utilizing all five factors may increase measurement sensitivity and predictive utility. © 2020 Taylor & Francis Group, LLC

Emotion-driven problem behaviour: The predictive utility of positive and negative urgency

Impulsive urgency describes the tendency to act rashly when experiencing extreme emotions. This Australian study aimed to investigate the predictive utility of impulsivity, including impulsive urgency (positive and negative), across a range of problem behaviours. Data from two community samples, one retrospective (n = 281) and one current (n = 604), were analysed using hierarchical regression to determine which facets of impulsivity, as assessed with a comprehensive scale (i.e. negative urgency, positive urgency, lack or premeditation, lack of perseverance, and sensation seeking), best predicted a series of problem behaviours (i.e. problem gambling, disorderly alcohol use, online gambling disorder, obsessive-compulsive disorder behaviours, and social media addiction). The impulsive urgency facets were shown to be significant predictors across the behaviours examined. More specifically, negative urgency was the strongest predictor of disorderly alcohol use, obsessive-compulsive disorder behaviours, and social media addiction. Positive urgency was associated with problem gambling and online gambling disorder behaviours. These findings suggest that impulsive urgency is a key contributing factor in many behavioural problems and that the valence of the urgency is an important consideration when addressing a broad range of psychopathologies

Investigating the presence of equine piroplasmosis in Ireland

Background: Equine piroplasmosis (EP) is a notifiable disease in Ireland and a significant concern to domestic and international equine industries. Information regarding EP presence in Ireland is currently limited. This retrospective surveillance study describes a serological and molecular analysis of blood samples submitted to the Irish Equine Centre for EP testing between January 2013 and April 2016. Methods: Following serological testing, seropositive samples were screened using a PCR targeting the 18S ribosomal RNA gene. Amplicon sequences were bioinformatically analysed to identify the parasite species and to assess genetic diversity. Results: From 2099 screened equine blood samples, 2.5 per cent and 1 per cent were seropositive for Theileria equi and Babesia caballi, respectively. T equi DNA was detected in 9 per cent of the seropositive samples while B caballi DNA was not detected in any sample. The T equi DNA sequences displayed no genetic diversity at this locus, in contrast to samples from the UK and from endemic areas. Conclusion: Detection of EP-seropositive and parasitaemic horses in Ireland indicates a clear and present health risk to the equine population. It is recommended that owners adopt appropriate biosecurity measures and that clinicians are mindful of this disease as a differential diagnosis

Fast X-ray tomography for the quantification of the bubbling-, turbulent- and fast fluidization-flow regimes and void structures

Multiple fluidization regimes were studied using X-ray tomography. Geldart B sand particles were used in a 14 cm (ID) column with a dual cyclone return system. Cross sectional solids concentration (/) was measured and the time averaged / ð /Þ decreased with velocity and axial height except in the turbulent regime where / remained constant. Radial profiles of / decreased to the centre, while all turbulent regime velocities resulted in similar radial / profiles. Results confirm the bubbling-turbulent transition velocity (Uc) determined from pressure fluctuations is a reliable quantification technique. The system exhibited slugging behaviour at higher bubbling regime velocities with voids taking on cylindrical shapes. Turbulent regime voids were characterised by elongated cylinders with diameters slightly less than the bubbling regime’s slugs or fast fluidization regime’s core annulus. Distribution curves of the / signal indicated a distinct dense phase in the bubbling and turbulent regime with a velocity independent solid concentration. Void velocity analysis suggested that the bubble linking algorithm was unable to detect fast rising voids at higher velocities.http://http://www.elsevier.com/locate/cejhb2013ai201
