Change management in technology projects: Using a comprehensive model of change management
Los proyectos tecnológicos, incluyendo la introducción de sistemas como los de tipo
CRM o ERP, tienen un impacto en las emociones, percepciones y resultados de las personas, así
como en la cultura organizacional de una empresa. También tienden a generar una serie de
problemáticas de gestión que son rara vez abordadas, y que pueden empujarlos al fracaso. Los gestores de tecnología deben aprender a gestionar los cambios asociados con la introducción de
nuevas tecnologías e innovaciones tecnológicas. La gestión del cambio, una disciplina relativamente
nueva, ofrece nuevas perspectivas para enfrentar los costos y riesgos asociados con los procesos de
cambio. Analiza aspectos críticos de la gestión como el rol del liderazgo, la coordinación, el diseño
de procesos y las estrategias de introducción. Se da un especial énfasis en habilidades blandas como
la gestión de emociones, la comunicación de objetivos y logros y el manejo de un aspecto crítico
como son las estructuras de poder y su evolución durante los procesos de cambioTechnology projects, including the introduction of new systems such as CRMs and
ERPs, have an impact on people`s emotions, perceptions and performance, as well as on
organizational and company culture. They also tend to raise a series of management issues that are
seldom addressed, causing many technology projects to fail. Technology managers must learn how to manage those changes associated with the introduction of
new systems and technical innovations. Change management, a relatively new discipline, offers new
perspectives to address the costs and risks associated with change processes. It analyzes critical
management issues such as the role of leadership, coordination, process design, and implementation
strategies. Special emphasis is given to soft skills such as managing emotions, communicating project
goals and achievements, and handling the critical issue of power structures and their evolution
during change processe
Learning Experience of Change management in Engineering Education
Los ingenieros en informática y computación en su vida profesional tienen que realizar múltiples proyectos de cambio
asociados a tecnología, sin embargo, en general no han sido formados para ello y cuando lo han sido usualmente es de
una forma teórica o muy centrada en el conocimiento intelectual. Este artículo muestra la experiencia de diseño y
realización de un curso de posgrado de gestión del cambio para ingenieros que trabajan en tecnología, computación e
informática. Este integra dos modelos. El primero un modelo sistémico de gestión del cambio. El segundo un modelo
de formación mediante metodologías experienciales que sitúan al estudiante como protagonista de su proceso de
aprendizaje. Esta unión ha generado un curso muy bien evaluado por sus estudiantes y que ha generado resultados
concretos en decenas de proyectos de cambio en organizaciones. La gestión del cambio, es una disciplina orientada al
liderazgo y la gestión de los procesos de cambio, aumentando su probabilidad de éxito y disminuyendo los costos y
los riesgos asociados. Analiza los problemas de gestión críticos, tales como el papel de la coordinación, diseño de
procesos y estrategias de implementación. Se presta especial atención a las habilidades blandas, tales como la gestión
de las emociones, la comunicación de los objetivos y logros del proyecto y la gestión del poder. Los ingenieros de hoy
necesitan habilidades y conocimientos para gestionar y movilizar a los procesos de cambio. Esta disciplina es central
para la gestión de proyectos en tecnología, computación e informática.In their professional endeavors, computer Engineers must participate in many projects associated with technological
change, even though they have not in general been trained to do so. Their training is theoretical, as well as
theoretically and intellectual focused. But today engineers need and new set of skills and knowledge to manage and
mobilize change processes. This article shows the experience of designing and conducting a postgraduate course on
change management for engineers working in technology, computing and information technology. It integrates two
models. The first is a systemic change management model. The second, a training model using experiential
methodologies that place students as key players in their learning process. This mix has been the basis of a series of
courses, which students positively appreciate, as well as in a series of change projects in organizations with positive
and measurable results. Change management is a discipline that focuses in the leadership and management of change
processes, increasing their chances of success and reducing costs and risks. It analyzes critical issues such as the role
of coordination, process design and implementation strategies management. Particular attention is given to soft skills
such emotion management, power management, and communication of project goals and achievements. Change
management has thus become a central discipline to project management technology, computing and information
technology
Abundance and Diversity of Earthworms in Managed and Non- Managed Fallow Lands of Calakmul Reserve of Campeche, Mexico
In Mexico, the best preserved tropical rain forest is found in Calakmul Reserve, where fallow land management has been established. Fallow lands are developed as a consequence of a successional vegetation process after clearing the primary vegetation and milpa production. Forty-nine sites were studied, where 17 were managed fallow lands, 24 non-managed fallow lands, and 8 tropical rain forests. Earthworms were collected at the end of the raining season, and four monoliths of 25 × 25 × 30 cm were developed per site according to the TSBF method. We observed how Zapatadrilus siboney, a native species was dominant in managed and non-managed fallow lands. Earthworm’s total biomass and density were not significantly different between the managed and non-managed fallow lands. Earthworm’s species richness was significantly low in non-managed fallow lands. We observed a strong correlation between earthworm density and richness with the age of the fallow lands (r2: 0.9 and 0.7; p < 0.05, respectively). The management type of the fallow land seems to affect earthworm biomasses (r2: 0.56; p < 0.05)
Estructura y composición de la vegetación leñosa de selvas en diferentes estadios sucesionales en el Ejido El Carmen II, Calakmul, México
Se analizó la diversidad florística de la selva mediana subperennifolia del ejido El Carmen II, Calakmul, Campeche, en diferentes estadios sucesionales en un área de 2700 m2. En nueve parcelas de 300 m2 se representó vegetación secundaria (acahual) con siete años de abandono, 15 años de abandono y selvas maduras, en las cuales se identifi caron y midieron todos los individuos leñosos con un DAP = 1 cm. Se encontraron 996 individuos de 78 especies distribuidas en 29 familias, las familias con mayor riqueza de especies fueron Fabaceae, Rubiaceae y Sapindaceae. Las especies con mayor abundancia en el área de estudio fueron Nectandra salicifolia, Pouteria reticulata, Croton icche y Bursera simaruba, esta última especie fue la única que se presentó en todas las parcelas de estudio. Las especies con mayor valor de importancia relativo (VIR) en los acahuales con siete años de abandono fueron Lysiloma latisiliquum, Bursera simaruba y Guettarda combsii; en los acahuales con 15 años de abandono las especies con mayor VIR fueron Nectandra salicifolia, Piscidia piscipula y Dendropanax arboreus; mientras en las parcelas de selva madura fueron Brosimum alicastrum, Manilkara zapota y Pouteria reticulata. Además se presentaron 15 especies sólo en parcelas de acahuales con siete años de abandono, cinco especies únicas en las parcelas de acahuales de 15 años y 18 especies únicas en las parcelas de selvas maduras. Concluimos que analizar la estructura y composición florística en vegetación en distintas fases sucesionales permite documentar mejor la diversidad florística de áreas que han sido altamente impactadas por distintos disturbio
Software Project Scheduling using the Hyper-Cube Ant Colony Optimization algorithm
U radu se daje prijedlog dizajna paradigme algoritma za optimizaciju kolonije mrava primjenom Hyper-Cube sustava za rješenje problema programiranja računarskog projekta (Software Project Scheduling Problem). Taj se NP-hard problem sastoji od davanja zaduženja zaposlenicima u svrhu smanjenja trajanja projekta i njegovih ukupnih troškova. To zaduženje mora zadovoljiti ograničenja problema i pitanje prvenstva među zadacima. Pristup prikazan ovdje koristi Hyper-Cube sustav za uspostavljanje eksplicitno multidimenzionalnog prostora za kontrolu ponašanja mravi. Time nam se omogućava autonomno vođenje istraživanja u cilju pronalaženja ohrabrujućih rješenja.This paper introduces a proposal of design of Ant Colony Optimization algorithm paradigm using Hyper-Cube framework to solve the Software Project Scheduling Problem. This NP-hard problem consists in assigning tasks to employees in order to minimize the project duration and its overall cost. This assignment must satisfy the problem constraints and precedence between tasks. The approach presented here employs the Hyper-Cube framework in order to establish an explicitly multidimensional space to control the ant behaviour. This allows us to autonomously handle the exploration of the search space with the aim of reaching encouraging solutions
Evaluation of PORT/PSI and SOFA scores in predicting in-hospital mortality of patients with COVID-19
Introduction: There is limited information analyzing the utility of different prognostic scores in predicting in-hospital mortality among patients with COVID-19. This study aimed to evaluate the performance of PORT/PSI and SOFA scores in predicting the in-hospital mortality of patients with COVID-19. Material and methods: This was an observational, analytical, and retrospective study that included consecutive patients hospitalized for COVID-19 from April 1, 2020, to May 31, 2020. The study population was characterized, and ROC analysis was performed and used to calculate the area under the curve of PORT/PSI and SOFA scores as well as the sensitivity, specificity, and predictive values. Results: A total of 151 patients were included, with a median age of 52 years (IQR 45-64); 69.5% were men, with a median BMI of 29.3 kg/m2 (IQR 25.5-34.7). Of the total, 102 patients died during hospitalization (67.5%). The areas under the ROC curves for predicting in-hospital mortality were 0.74 (95% CI 0.67-0.81) for the SOFA score and 0.85 (95% CI 0.78-0.90) for the PORT/PSI score. When compared, the PORT/PSI score predicted mortality significantly better than the SOFA score (p: 0.01). Conclusions: The PORT/PSI score is a good tool to predict in-hospital mortality in patients with COVID-19

The effects of interset rest on adaptation to 7 weeks of explosive training in young soccer players
The aim of the study was to compare the effects of plyometric
training using 30, 60, or 120 s of rest between sets on explosive
adaptations in young soccer players. Four groups of athletes
(age 10.4 ± 2.3 y; soccer experience 3.3 ± 1.5 y) were randomly
formed: control (CG; n = 15), plyometric training with 30 s
(G30; n = 13), 60 s (G60; n = 14), and 120 s (G120; n = 12) of
rest between training sets. Before and after intervention players
were measured in jump ability, 20-m sprint time, change of
direction speed (CODS), and kicking performance. The training
program was applied during 7 weeks, 2 sessions per week, for a
total of 840 jumps. After intervention the G30, G60 and G120
groups showed a significant (p = 0.0001 – 0.04) and small to
moderate effect size (ES) improvement in the countermovement
jump (ES = 0.49; 0.58; 0.55), 20 cm drop jump reactive strength
index (ES = 0.81; 0.89; 0.86), CODS (ES = -1.03; -0.87; -1.04),
and kicking performance (ES = 0.39; 0.49; 0.43), with no
differences between treatments. The study shows that 30, 60,
and 120 s of rest between sets ensure similar significant and
small to moderate ES improvement in jump, CODS, and kicking
performance during high-intensity short-term explosive training
in young male soccer players
