“…Aunque ETA al cuadrado se interpreta como R 2 , su interpretación debe hacerse con precaución, ya que presenta críticas respecto a proporcionar sesgo (Iacobucci et al, 2023) porque "sobrestima la proporción poblacional de la varianza explicada" (Bakeman, 2005, p. 383). Por esta razón, se recomienda utilizar ETA parcial al cuadrado; sin embargo, en el caso de un ANOVA de una vía, el tamaño del efecto es el mismo para ETA al cuadrado y ETA parcial al cuadrado (Iacobucci et al, 2023).…”

En los países en desarrollo, el emprendimiento emerge como una alternativa vital ante el desempleo, aunque para ello se requiere el desarrollo de habilidades emprendedoras durante la etapa universitaria, ya que esto eleva significativamente las posibilidades de éxito en el momento en que se decide establecer un negocio propio. Sin embargo, en el contexto del empleo juvenil, la falta de experiencia o deficiencias en habilidades para emprender pueden obstaculizar la continuidad de nuevos proyectos empresariales. Esta investigación, por tanto, tiene como objetivo principal determinar el nivel de adquisición de competencias emprendedoras en estudiantes de una universidad pública que se encuentran en el último año de licenciatura en negocios y que participan activamente en iniciativas institucionales para fomentar el emprendimiento. Asimismo, se busca identificar posibles disparidades de género y diferencias entre aquellos con antecedentes previos en emprendimiento. Mediante un enfoque de muestreo no probabilístico, se recopilaron datos de 210 estudiantes a través de una encuesta en línea. Luego, se empleó un análisis de conglomerados utilizando una metodología de dos pasos, lo que permitió identificar cinco conglomerados que fueron posteriormente evaluados en su estructura mediante un análisis de varianza (ANOVA). Los resultados principales revelaron que en el ámbito de la educación superior pública, se ha promovido activamente el enfoque en el emprendimiento, lo que ha facilitado la adquisición efectiva de competencias profesionales, metodológicas, comunicativas, personales y de trabajo en equipo en la mayoría de los estudiantes. Además, se observó que los participantes de género masculino y aquellos con experiencia previa en el desarrollo de negocios mostraron un mayor nivel de adquisición de competencias emprendedoras. En consecuencia, esta investigación sugiere la necesidad de ajustes en los planes de estudio universitarios para incorporar contenidos que promuevan la identificación, desarrollo y aplicación de oportunidades de negocio, de modo que se promueva la inserción laboral de los graduados tanto en emprendimientos propios como en empleos asalariados.

“…To test the proposed conceptual model and hypotheses, the data were tested using PROCESS version 3.5 Model 85 with 5,000 bootstrap resamples and a 95% confidence interval (Hayes, 2013). As this study analysis utilises regressions in PROCESS as opposed to ANOVAs, R 2 are reported to detail the effect sizes as opposed to eta-squared ( η 2 ), omega-squared ( ω 2 ) and epsilon-squared ( ε 2 ) (de Hues, 2012; Iacobucci et al ., 2022).…”

PurposeThis paper aims, first, to examine artificial intelligence (AI) vs human delivery of financial advice; second, to examine the serial mediating roles of emotion and trust between AI use in the financial service industry and their impact upon marketing outcomes including word of mouth (WOM) and brand attitude; and third, to examine how political ideology moderates' consumers' reactions to AI financial service delivery.Design/methodology/approachA review of the extant literature is conducted, yielding seven hypotheses underpinned by affect-as-information theory. The hypotheses are tested via three online scenario-based experiments (n = 801) using Process Macro.FindingsThe results of the three experiments reveal consumers experience lower levels of positive emotions, specifically, affection, when financial advice is provided by AI in comparison to human employees. Secondly, across the three experiments, conservative consumers are shown to perceive somewhat similar levels of affection in financial advice provided by AI and human employees. Whereas liberal consumers perceive significantly lower levels of affection when serviced by AI in comparison to conservatives and human employee financial advice. Thirdly, results reveal affection and trust to be serial mediators which explain consumers' WOM and brand attitudes when financial services are provided by AI. Fourthly, the investment type plays an important role in consumers’ reactions to the use of AI.Originality/valueTo the best of the authors’ knowledge, this research is one of the first to study political ideology as a potential moderator of consumers’ responses to AI in financial services, providing novel contributions to the literature. It further contributes unique insights by examining emotional responses to AI and human financial advice for different amounts and types of investments using a comprehensive approach of examining both valence and discrete emotions to identify affection as a key explanatory emotion. The study further sheds insights relating to how emotions (affection) and trust mediate the relationship between AI and WOM, and brand attitudes, demonstrating an affect-attitude psychological sequence that explains consumers’ reactions to AI in financial services.

“…The significance threshold was set at 0.05, and a Greenhouse-Geisser correction was applied whenever the assumption of Sphericity was violated (indicated by ε). Effect sizes were indicated with Cohen’s d for t tests and partial eta squared for ANOVAs [ 57 , 58 ].…”

This study investigates whether humans recognize different emotions conveyed only by the kinematics of a single moving geometrical shape and how this competence unfolds during development, from childhood to adulthood. To this aim, animations in which a shape moved according to happy, fearful, or neutral cartoons were shown, in a forced-choice paradigm, to 7- and 10-year-old children and adults. Accuracy and response times were recorded, and the movement of the mouse while the participants selected a response was tracked. Results showed that 10-year-old children and adults recognize happiness and fear when conveyed solely by different kinematics, with an advantage for fearful stimuli. Fearful stimuli were also accurately identified at 7-year-olds, together with neutral stimuli, while, at this age, the accuracy for happiness was not significantly different than chance. Overall, results demonstrates that emotions can be identified by a single point motion alone during both childhood and adulthood. Moreover, motion contributes in various measures to the comprehension of emotions, with fear recognized earlier in development and more readily even later on, when all emotions are accurately labeled.
