Culture dimensions in software development industry: The effects of mentoring
Software development is a human centric and sociotechnical activity and like all human activities is influenced by cultural factors. However, software engineering is being further affected because of the globalization in software development. As a result, cultural diversity is influencing software development and its outcomes. The software engineering industry, a very intensive industry regarding human capital, is facing a new era in which software development personnel must adapt to multicultural work environments. Today, many organizations present a multicultural workforce which needs to be managed. This paper analyzes the influence of culture on mentoring relationships within the software engineering industry. Two interesting findings can be concluded from our study: (1) cultural differences affect both formal and informal mentoring, and (2) technical competences are not improved when implementing mentoring relationships
Pedagogical approach of grade 7 teachers in teaching the learning competency of integers
This research addresses the intricate challenges of teaching integers in middle school mathematics. Focusing on grade 7 teachers, the study explores strategies to enhance integers' teaching-learning competency, revealing nuanced approaches employed by three teachers. Through qualitative methods, specifically in-depth interviews, the research uses an exploratory approach to unravel the underlying strategies shaping the teaching of integers. Key findings underscore integers as a formidable learning competency for grade 7 students, particularly in operations like addition and subtraction. The most effective pedagogical approach, encapsulated in the 3Rs — Reaching, Representing, Recommending — involves drill exercises for foundational concepts, integrating manipulatives like algebra tiles and coloured tiles, and advocating for continuous manipulative use with persistent drill exercises and integrating technology. These identified themes emphasize the need for a uniform understanding among teachers during discussions to ensure a cohesive and effective teaching strategy. Recognizing these strategies is crucial for addressing the existing learning gap and advancing grade 7 students' competency in dealing with integers. The research contributes valuable insights to the academic discourse, offering effective pedagogical practices and fostering a more robust foundation for mathematical understanding at the middle school level
La página web de la previsora como desventaja competitiva frente a las aseguradoras colombianas
El documento está organizado en cinco capítulos así: el primer capítulo introduce la definición del canal de distribución y el comercio electrónico. El segundo se centra en conocer las generalidades del sector asegurador colombiano. El tercero está enfocado en la reseña histórica de la Previsora Seguros y su evolución en canales de distribución. El cuarto, analiza algunos sitios web de las principales compañías aseguradoras en Colombia, lo cual permitió conocer el enfoque y uso de sus sitos en Internet, además de identificar como hasta hoy la principal función que ejercen estos sitios es ser una vitrina de información de productos y servicios, existiendo escaso desarrollo de los mercados electrónicos de seguros, y muy pocos elementos que permitan la atención integral de los clientes a través de este canal. Finalmente está el capítulo de conclusiones y recomendaciones para que la página web de la Previsora Seguros se convierta en un canal de distribución competitivo frente al mercado y las demás aseguradoras, generando de esta manera valor agrado a la empresa y al cliente fina
Uncovering the host galaxy of the -ray-emitting narrow-line Seyfert 1 galaxy FBQS J1644+2619
The discovery of -ray emission from radio-loud narrow-line Seyfert 1
(NLSy1) galaxies has questioned the need for large black hole masses (> 10
M) to launch relativistic jets. We present near-infrared data of the
-ray-emitting NLSy1 FBQS J1644+2619 that were collected using the
camera CIRCE (Canarias InfraRed Camera Experiment) at the 10.4-m Gran
Telescopio Canarias to investigate the structural properties of its host galaxy
and to infer the black hole mass. The 2D surface brightness profile is modelled
by the combination of a nuclear and a bulge component with a S\'ersic profile
with index = 3.7, indicative of an elliptical galaxy. The structural
parameters of the host are consistent with the correlations of effective radius
and surface brightness against absolute magnitude measured for elliptical
galaxies. From the bulge luminosity, we estimated a black hole mass of
(2.10.2) 10 M, consistent with the values
characterizing radio-loud active galactic nuclei.Comment: 5 pages, 3 figures, 1 table. Monthly Notices of the Royal

Contenido de ADN nuclear y nivel de ploidía en genotipos apomícticos de buffelgrass
Buffelgrass [Pennisetum ciliare (L.) Link syn. Cenchrus ciliaris L.] is a polyploid fodder grass that has mostly apomictic reproduction. The wide genetic and cytological diversity present in the species indicates that the active field collection of the IFRGV - INTA might contain individuals with different ploidy levels. The aims of this work were to determine the nuclear DNA content and ploidy level of an introduced apomictic germplasm of buffelgrass. Cytological studies showed different ploidy levels in the germplasm. Genetic resources include tetraploid (2n = 4x = 36) and aneuploid (2n = 43 and 44) individuals. The 10 materials that exhibited 2C values ranging between 3.04 and 3.17 pg were tetraploid cytotypes. The values of the four aneuploid individuals with 43 chromosomes ranged between 3.83 and 3.86 pg, whereas aneuploid individual with 44 chromosomes had 2C value of 3.94 pg. Number of chromosomes and nuclear DNA content were correlated. In addition, a model equation was obtained, which might be used to estimate DNA ploidy value in buffelgrass genotypes.Fil: Carloni, Edgardo José.

Ancient climate changes and Andes uplift, rather than Last Glacial Maximum, affected distribution and genetic diversity patterns of the southernmost mycoheterotrophic plant Arachnitis uniflora Phil. (Corsiaceae)
Arachnitis uniflora (Corsiaceae) is a mycoheterotrophic plant native to South America that grows in tropical semi-humid forests of Peru and Bolivia, in the temperate Andean-Patagonian forests of Argentina and Chile, and in the moorlands of Malvinas/Falkland Islands. This widely distributed and disjunct species offers the opportunity to explore the dynamics of evolutionary processes using phylogeographic approaches, spatio-temporal and paleodistribution reconstructions; these tools allow us to test how ancient geological events and climate changes occurred in the Miocene-Pliocene and how the more recent Pleistocene events affected diversification, demography, and genetic diversity patterns over space and time. We sampled 28 sites, covering the whole geographic range of Arachnitis uniflora. We amplified and sequenced the internal transcribed spacer (ITS), 18S rRNA, and 26S rRNA nuclear regions in 141 individuals, and the plastid 16S rRNA gene in a subset of 90 individuals. In order to reconstruct the evolutionary history of the species, we performed phylogeographic, dating analyses, spatio-temporal diffusion models, and species paleo-distribution projections. Arachnitis uniflora has an ancient origin and diversified during the Late Miocene, splitting into two genetic groups named the Northern and Patagonian groups. Haplotype diversification of both groups dated about late Miocene and early Pliocene. We detected demographic expansion at the early Pleistocene, and most diversifications and colonizations occurred before the LGM. Paleo-distribution modelling predicted few changes of the species distribution from 800 Mya to the present, showing only a range expansion at the east during the LGM. Four areas of high genetic diversity were identified suggesting refugial areas where the species persisted. Orogeny and climate changes promoted by the Andes uplift during the Late Miocene produced the main ancient genetic divergence due to the formation of the Arid Diagonal. Most diversification, colonizations, and demographic processes occurred from early Pliocene to the beginning of the Pleistocene before the Great Patagonian Glaciation, revealing a low influence of the LGM glaciations on the species evolutionary history.Fil: Renny, Mauricio Eduardo.

La belleza de lo inútil
La belleza de lo inútil es un proyecto que pretende acercar el arte al
ámbito cotidiano. Esto lo hace a partir de un ejercicio de domismo1
,
realizando una serie de muebles donde la función y el diseño no están
conectados, de tal forma que se obtienen objetos inútiles, para así
diferenciarlos de los objetos de diseño al uso, por lo que no sólo
operan en un plano estéticamente superficial. La temática, además, se
centra en el cosmos haciendo que lo exterior se introduzca en el
domus. Este proyecto plantea una búsqueda del conocimiento
personal a través de intervenir lo que nos rodea.The beauty of the useless is a project that aims to bring art to everyday
life. It is achieved by an exercise of domismo1
, producing furniture in
which function and design are not related, in order to obtain useless
objects, aiming to separate them from simple design objects. In this
way, they wouldn´t just operate in a aesthetically superficial
dimension. The topic, besides, focuses on the cosmos causing the
outside to access the domus. This project sets out a search for personal
knowledge through thanks to our surroundings
