Love Thy Neighbor: La Vida Musical De Justo Almario
No full textYa mencionamos la importancia y el significado que tenía para Justo hacer parte de esta agrupación, pero aunque lo hayamos dicho y usted como lector lo haya leído, creo que escuchar la voz de Kenny Burrell presentando a sus acompañantes en el quinteto y luego escuchar la calidad de la agrupación, incluyendo el solo de Justo Almario en el saxofón tenor, nos puede transportar un poco a las sensaciones que él pudo tener, además de que nos permite disfrutar de momentos musicales que, personalmente, como amante del jazz, como músico y saxofonista, y como biógrafo de nuestro personaje, me atrevo a calificar como sublimes
Love Thy Neighbor: La Vida Musical De Justo Almario
No full textÉl estaba leyendo una revista que se llama DownBeat. Es una revista de música en los Estados Unidos en donde él lee que están ofreciendo unas becas para estudiar en Boston, en Berklee, y me dice: “mira Justo, tú debes aplicar a esto”, entonces decía: para la aplicación se necesita hacer una grabación y mandar a lo mejor un tema que tú hayas arreglado, o una composición. Y así lo hicimos, él me ayudó, tocó el piano, yo toqué… creo que toqué esta canción
Guidance and support of women in engineering programs at Universidad Tecnologica de Bolivar
No full textGender equality is one of the sustainable development goals. In STEM areas, it is a requirement to expand and improve women's careers. To increase the participation of women in STEM it is not enough to attract more young women to these programs. It is necessary to provide orientation during the academic programs and ensure safe and rewarding environments so that women can succeed in their studies. The Faculty of Engineering of Universidad Tecnológica de Bolívar has gender gaps in most of its programs and several strategies are being implemented to overcome this situation. This paper analyzes five factors to guide and support women in engineering programs: academic success, protection of women, scholarships and financial assistance, international mobility, and leadership. We present several activities and strategies developed in the last three years in these five factors. The impacts of these strategies cannot be evaluated yet, but we expect that they can improve the well-being of women in engineering and contribute to the reduction of the gender gaps. © 2023 IEEE
As redes sociais como lugares de memória: diálogos cidadãos através da fotografia no Facebook] [Redes sociales digitales como lugares de memoria: diálogos ciudadanos a través de la fotografía en Facebook
No full textThis paper addresses the potential of social media as places for citizen dialogue around memory and cultural identity of territories and their inhabitants. From the perspective of cultural anthropology and memory studies, an exploratory research is presented based on the content analysis of two Facebook groups linked to the city of Cartagena de Indias (Colombia), accompanied by qualitative interviews with their administrators and with historians of the territory. The results explain some of the factors that contribute to the popularity of these virtual groups, based on the use of vernacular photography, and show how digital social networks have come to complement or replace functions that were once restricted to public and academic institutions, museums and archives. It is concluded that, despite their limitations, these groups, born in a specific historical and technological context, constitute important virtual places of memory. © 2022 Scientific Association Icono14.

Tendencias en la formación de Gerentes de Proyectos en Colombia: Revisión de la Oferta a Nivel de Especializaciones
No full textThe purpose of this work was to
investigate the offer of specialization programs
in project management in Colombia, which
allowed to characterize the offer, the study
plans, the courses included in their curricular
networks and the main coincidences between
these programs. Additionally, the training trend
in the discipline, its relationship with the
geographical area where it is offered and the
degree of alignment of the Colombian offer with
training worldwide, was identified
Concentrations of Airborne Cultivable Fungi at a Higher Education Institution in Cartagena de Indias, Colombian Caribbean
No full textBioaerosols are as small particles suspended in air that contain several microorganisms (bacteria, fungi, and viruses). These particles are studied because of the possible impacts that they have on the health of humans and animals in open and closed spaces. In this study, the presence of airborne fungi presents in a Higher Education Institution (HEI) of the city of Cartagena de Indias, Colombian Caribbean was evaluated. Over 4 months (June–October 2018), 128 fungal samples were collected using a two-stage cascade impactor, and the fungi present in these samples were counted, characterized, and identified. Bioaerosol concentrations were correlated with meteorological data from the Rafael Núñez Airport meteorological station to establish the possible influence of these factors on the presence of bioaerosols. The results obtained showed an average concentration of fungal aerosols of 123.71 ± 17.97 UFC/m3, with the highest proportion occurring in the morning. The predominant genera were Aspergillus (60.8%), followed by Penicillium (24.5%) and Fusarium (9.3%). According to the correlations obtained from a multivariate analysis, the meteorological parameters did not influence the presence of microorganisms at the HEI studied; however, a possible influence of emission sources such as vegetation and industry is suggested. © 2022, The Author(s) under exclusive licence to Institute of Earth Environment, Chinese Academy Sciences
El enfoque cultural del desarrollo y los derechos culturales como propuesta para la redimensión de la reparación colectiva
No full textTo give superficial importance to the cultural
aspect in the context of collective reparation,
particularly to the effects caused in this area to
groups and communities of victims, can have
serious repercussions on the comprehensiveness of
reparation and its transformative effect. In this sense,
a reflection on collective reparation that takes as
an essential postulate the inclusion of the cultural
aspect in the process is necessary, which constitutes
the main objective of this work. For this purpose,
the theoretical notes of the cultural approach to
development and other approaches that nurture it
are methodologically picked up as key elements
towards a resizing of collective reparation. Finally,
this reparation allows enhancing their transformative
claim and opens the door to local and community
development processes to make possible both the
agency of their rights as victims, as well as their rights
as individuals and citizensOtorgar una importancia superficial a
lo cultural en el marco de la reparación
colectiva, particularmente a las
afectaciones causadas en este ámbito
a grupos y comunidades de víctimas,
puede generar serias repercusiones
sobre la integralidad de la reparación y
su efecto transformador. En ese sentido,
se hace necesaria una reflexión en torno
a la reparación colectiva que tome como
postulado esencial la inclusión de lo
cultural en el proceso, lo que constituye
el objetivo principal de este trabajo.
Para ello, se retoman metodológicamente
los apuntes teóricos del enfoque cultural
del desarrollo y otros enfoques que lo
alimentan, como elemento clave hacia
una redimensión formal y operativa de
la reparación colectiva. Finalmente, esta
redimensión permite potenciar su
pretensión trasformadora y abrir la
puerta a procesos de desarrollo local y
comunitario, para hacer posible tanto la
agencia de sus derechos como víctimas,
así como de sus derechos en tanto
personas y ciudadanía
Design and simulation of techniques for mitigation of harmonic distortion in a three-phase rectifier
No full textRectifiers are electrical devices that receive an alternating signal and deliver a direct current signal at their output, this process by which they transform one type of energy to another is known as rectification. This type of device incorporates a phenomenon called harmonic distortion into the electrical network, which consists of malformations presented in the waveform of the alternating signal from which it feeds, which generate unwanted effects on electrical systems. Because of this, this work presents the combination of two harmonic distortion mitigation strategies (12-pulse multilevel converter and harmonic frequency tuned filtering stage) in order to reduce total harmonic distortion levels generated by a three-phase rectifier. © Published under licence by IOP Publishing Ltd
Advancements in quantum machine learning for intrusion detection: A comprehensive overview
No full textThis chapter provides a comprehensive overview of the recent developments in quantum machine
learning for intrusion detection systems. The authors review the state of the art based on the published
work “Quantum Machine Learning for Intrusion Detection of Distributed Denial of Service Attacks: A
Comparative View” and its relevant citations. The chapter discusses three quantum models, including
quantum support vector machines, hybrid quantum-classical neural networks, and a two-circuit ensemble
model, which run parallel on two quantum processing units. The authors compare the performance of
these models in terms of accuracy and computational resource consumption. Their work demonstrates
the effectiveness of quantum models in supporting current and future cybersecurity systems, achieving
close to 100% accuracy, with 96% being the worst-case scenario. The chapter concludes with future
research directions for this promising field
Love Thy Neighbor: La Vida Musical De Justo Almario
No full textMongo Santamaría me llamó a trabajar con él. Él vino a la ciudad y me dijo… le habían dado mi número, y me llamó y me dijo: “hombre, mi saxofonista no tocará, ¿podrías venir y tocar esta noche? Él viene mañana”, así que fui y toqué esa noche. Al final de la noche Mongo me dice: “¿Por qué no te quedas toda la semana?, ¿puedes tocar con nosotros toda la semana?”, ok. Terminamos la semana completa y
dijo: “hombre, en dos semanas voy a ir a Georgia, Atlanta, ¿puedes ir y tocar?” [risas]. Fui y entonces me preguntó si podía viajar a Nueva York y volverme un miembro regular de la banda, así que fui y hablé con los profesores y realicé mis exámenes, todo lo que debía hacer, y ¡pum! Me gradué y me fui a Nueva York (traducción propia)
