Predicting university performance in psychology: the role of previous performance and discipline-specific knowledge

Recent initiatives to enhance retention and widen participation ensure it is crucial to understand the factors that predict students' performance during their undergraduate degree. The present research used Structural Equation Modeling (SEM) to test three separate models that examined the extent to which British Psychology students' A-level entry qualifications predicted: (1) their performance in years 1-3 of their Psychology degree, and (2) their overall degree performance. Students' overall A-level entry qualifications positively predicted performance during their first year and overall degree performance, but negatively predicted their performance during their third year. Additionally, and more specifically, students' A-level entry qualifications in Psychology positively predicted performance in the first year only. Such findings have implications for admissions tutors, as well as for students who have not studied Psychology before but who are considering applying to do so at university

On Slow Light as a Black Hole Analogue

Although slow light (electromagnetically induced transparency) would seem an ideal medium in which to institute a ``dumb hole'' (black hole analog), it suffers from a number of problems. We show that the high phase velocity in the slow light regime ensures that the system cannot be used as an analog displaying Hawking radiation. Even though an appropriately designed slow-light set-up may simulate classical features of black holes -- such as horizon, mode mixing, Bogoliubov coefficients, etc. -- it does not reproduce the related quantum effects.

A Framework for Organizational Compliance Management Tactics

Abstract. Organizational compliance with laws, industrial standards, procedures and enterprise architectures has become a highly relevant topic for both practitio-ners and academics. However, both the fundamental insights into compliance as a concept and the tactics for bringing an organization into a compliant state have been described in a fragmented manner. Using literature from various disciplines, this paper presents two contributions. First, it describes the fundamental concepts regarding compliance. Second, it presents a framework in which the various tactics for achieving organizational compliance can be positioned

Anthropogenic Space Weather

Anthropogenic effects on the space environment started in the late 19th century and reached their peak in the 1960s when high-altitude nuclear explosions were carried out by the USA and the Soviet Union. These explosions created artificial radiation belts near Earth that resulted in major damages to several satellites. Another, unexpected impact of the high-altitude nuclear tests was the electromagnetic pulse (EMP) that can have devastating effects over a large geographic area (as large as the continental United States). Other anthropogenic impacts on the space environment include chemical release ex- periments, high-frequency wave heating of the ionosphere and the interaction of VLF waves with the radiation belts. This paper reviews the fundamental physical process behind these phenomena and discusses the observations of their impacts.Comment: 71 pages, 35 figure

Formación docente para la implementación de la plataforma virtual Moodle como recurso didáctico en educación básica secundaria

1 recurso en línea (288 páginas) : ilustraciones color, tablas.Este estudio describe una experiencia llevada a cabo en entornos virtuales de aprendizaje Moodle, donde se planteó la utilización de la Educación Virtual como recurso didáctico educativo. A partir de un proceso de formación docente para la implementación de la plataforma virtual Moodle como recurso didáctico de enseñanza, se analizó si se presentaron cambios significativos en las competencias digitales: Pedagógica, tecnológica, comunicativa y de gestión, y a partir de ello se mejoró el desempeño pedagógico de los educadores; de igual forma se indago sobre la posibilidad de que las plataformas virtuales como Moodle puedan convertirse en una alternativa viable que pueda dar respuesta a los nuevos retos educativos relacionados con los ambientes virtuales de aprendizaje para dinamizar el proceso educativo. Como objetivo general del estudio se planteó Identificar las competencias digitales que poseen los docentes para el uso y administración de la plataforma Moodle, en el nivel de educación básica secundaria y media de la Institución Educativa Técnica de Monguí, para implementar un programa de formación encaminado a fortalecer dichas competencias. La metodología empleada en el estudio fue de tipo mixto, porque involucra aspectos cuantitativos como la medición de las variable competencias digitales desarrolladas por los docentes para el empleo de la plataforma virtual Moodle, desde el paradigma cualitativo se tuvieron en cuenta las opiniones y conceptos de los sujetos participantes en el estudio; de los resultados obtenidos se encontró que los programas de formación docente para el uso didáctico de las TIC en entornos de aprendizaje virtual como la plataforma Moodle, cuando son orientados con un modelo pedagógico activo diferente al catedrático, permiten que los educadores apropien el uso de estas tecnologías y sean gestores de proyectos que dinamizan el proceso enseñanza – aprendizaje, al brindar al estudiante la posibilidad de ser un agente participativo y por su puesto al educador ser guía y orientador en el proceso educativo.This study describes an experience carried out in Moodle virtual learning environments, where the use of Virtual Education as an educational didactic resource was proposed. From a process of teacher training for the implementation of the Moodle virtual platform as a didactic teaching resource, it was analyzed if there were significant changes in the digital competences: Pedagogical, technological, communicative and management, and from this the pedagogical performance of educators; In the same way, I inquired about the possibility that virtual platforms such as Moodle could become a viable alternative that could respond to new educational challenges related to virtual learning environments to boost the educational process. The general objective of the study was to identify the digital competences that teachers possess for the use and administration of the Moodle platform, at the level of secondary and secondary education of the Technical Educational Institution of Monguí, to implement a training program aimed at strengthen these competences The methodology used in the study was of mixed type, because it involved quantitative aspects such as the measurement of the variable digital competences developed by teachers for the use of the Moodle virtual platform, from the qualitative paradigm the opinions and concepts of the subjects participating in the study; From the results obtained it was found that the teacher training programs for the didactic use of ICT in virtual learning environments such as the Moodle platform, when they are oriented with an active pedagogical model different from the professor, allow educators to appropriate the use of these technologies and managers of projects that dynamize the teaching - learning process, giving the student the possibility of being a participative agent and of course the educator being a guide and guidance in the educational process.Bibliografía y webgrafía: páginas 196-205MaestríaMagíster en TIC Aplicadas a las Ciencias de la Educació

Proteogenomic landscape of breast cancer tumorigenesis and targeted therapy

The integration of mass spectrometry-based proteomics with next-generation DNA and RNA sequencing profiles tumors more comprehensively. Here this "proteogenomics" approach was applied to 122 treatment-naive primary breast cancers accrued to preserve post-translational modifications, including protein phosphorylation and acetylation. Proteogenomics challenged standard breast cancer diagnoses, provided detailed analysis of the ERBB2 amplicon, defined tumor subsets that could benefit from immune checkpoint therapy, and allowed more accurate assessment of Rb status for prediction of CDK4/6 inhibitor responsiveness. Phosphoproteomics profiles uncovered novel associations between tumor suppressor loss and targetable kinases. Acetylproteome analysis highlighted acetylation on key nuclear proteins involved in the DNA damage response and revealed cross-talk between cytoplasmic and mitochondrial acetylation and metabolism. Our results underscore the potential of proteogenomics for clinical investigation of breast cancer through more accurate annotation of targetable pathways and biological features of this remarkably heterogeneous malignancy
