Operatividad de las reglas del concepto integrativo de desarrollo sostenible
Con la finalidad de medir el concepto de desarrollo sostenido, en el presente trabajo se plantean criterios y bases conceptuales para operacionalizar las variables e indicadores de las reglas de la teoría integrativa del desarrollo sostenido. Operativizar el concepto integrativo de desarrollo es posible y objetivo, la complejidad y la interrelación entre variables e indicadores es evidente, el factor social es de vital importancia porque nos permite concretar consensuadamente los indicadores después del análisis de cada variable, lo que significa que el desarrollo humano como unidad central es de vital importancia. Pues el mayor porcentaje de la operacionalización de los indicadores son de carácter volitivo y humano
Horizontal flow fields observed in Hinode G-band images II. Flow fields in the final stages of sunspot decay
We present a subset of multi-wavelengths observations obtained with the
Japanese Hinode mission, the Solar Dynamics Observatory (SDO), and the Vacuum
Tower Telescope (VTT) at Observatorio del Teide, Tenerife, Spain during the
time period from 2010 November 18-23. Horizontal proper motions were derived
from G-band and Ca II H images, whereas line-of-sight velocities were extracted
from VTT Echelle H-alpha 656.28 nm spectra and Fe I 630.25 nm spectral data of
the Hinode/Spectro-Polarimeter, which also provided three-dimensional magnetic
field information. The Helioseismic and Magnetic Imager on board SDO provided
continuum images and line-of-sight magnetograms as context for the
high-resolution observations for the entire disk passage of the active region.
We have performed a quantitative study of photospheric and chromospheric flow
fields in and around decaying sunspots. In one of the trailing sunspots of
active region NOAA 11126, we observed moat flow and moving magnetic features
(MMFs), even after its penumbra had decayed. We also noticed a superpenumbral
structure around this pore. MMFs follow well-defined, radial paths from the
spot all the way to the border of a supergranular cell surrounding the spot. In
contrast, flux emergence near the other sunspot prevented it from establishing
such well ordered flow patterns, which could even be observed around a tiny
pore of just 2 Mm diameter. After the disappearance of the sunspots/pores a
coherent patch of abnormal granulation remained at their location, which was
characterized by more uniform horizontal proper motions, low divergence values,
and diminished photospheric Doppler velocities. This region, thus, differs
significantly from granulation and other areas covered by G-band bright points.
We conclude that this peculiar flow pattern is a signature of sunspot decay and
the dispersal of magnetic flux.Comment: 13 pages, 11 figures, accepted for publication in Astronomy and

Programming Skeletal Muscle Metabolic Flexibility in Offspring of Male Rats in Response to Maternal Consumption of Slow Digesting Carbohydrates during Pregnancy
Skeletal muscle plays a relevant role in metabolic flexibility and fuel usage and the
associated muscle metabolic inflexibility due to high-fat diets contributing to obesity and type 2
diabetes. Previous research from our group indicates that a high-fat and rapid-digesting carbohydrate
diet during pregnancy promotes an excessive adipogenesis and also increases the risk of non-alcoholic
fatty liver disease in the offspring. This effect can be counteracted by diets containing carbohydrates
with similar glycemic load but lower digestion rates. To address the role of the skeletal muscle in
these experimental settings, pregnant rats were fed high-fat diets containing carbohydrates with
similar glycemic load but different digestion rates, a high fat containing rapid-digesting carbohydrates
diet (HF/RD diet) or a high fat containing slow-digesting carbohydrates diet (HF/SD diet). After
weaning, male offspring were fed a standard diet for 3 weeks (weaning) or 10 weeks (adolescence)
and the impact of the maternal HF/RD and HF/SD diets on the metabolism, signaling pathways
and muscle transcriptome was analyzed. The HF/SD offspring displayed better muscle features
compared with the HF/RD group, showing a higher muscle mass, myosin content and differentiation
markers that translated into a greater grip strength. In the HF/SD group, metabolic changes such
as a higher expression of fatty acids (FAT/CD36) and glucose (GLUT4) transporters, an enhanced
glycogen content, as well as changes in regulatory enzymes such as muscle pyruvate kinase and
pyruvate dehydrogenase kinase 4 were found, supporting an increased muscle metabolic flexibility
and improved muscle performance. The analysis of signaling pathways was consistent with a better
insulin sensitivity in the muscle of the HF/SD group.This research was funded by European Union’s Seventh Framework Programme (FP7/2007–2013):

Aislamiento y sensibilidad de bacterias de ganglios cervicales en cuyes (Cavia porcellus) con linfadenitis en granjas de crianza familiar comercial de Cajamarca, Perú
The aim of this study was to identify the etiological agent of lymphadenitis in guinea pigs from five commercial family breeding farms in Cajamarca, Peru, as well as to determine the sensitivity of the agents found against antibacterial frequently used in the area (amoxicillin, ciprofloxacin, nitrofurantoin, cephalexin, tetracycline, trimethoprim/sulfamethoxazole, and penicillin). Five guinea pigs with clinical signs of lymphadenitis were obtained and samples were taken from the affected cervical lymph nodes. Bacterial isolation was carried out on blood agar and MacConkey agar and the antibiogram was carried out according to the Kirby-Bauer method. The etiological agent was Trueperella pyogenes, highly sensitive to nitrofurantoin and resistant to penicillin.El trabajo tuvo como objetivo identificar al agente etiológico de linfadenitis en cuyes de cinco granjas de crianza familiar comercial de Cajamarca, Perú, así como determinar la sensibilidad de los agentes encontrados frente a antibacterianos de uso frecuente en el lugar (amoxicilina, ciprofloxacino, nitrofurantoína, cefalexima, tetraciclina, trimetoprima/sulfametoxazol y penicilina). Se obtuvieron cinco cuyes con signos clínicos de linfadenitis y se tomaron muestras de los ganglios cervicales afectados. Se hizo el aislamiento bacteriano en agar Sangre y agar MacConkey y el antibiograma según el método de Kirby-Bauer.

Liderazgo Personalista Integral. Un modelo para el liderazgo en las organizaciones
In the study of leadership ethics in organizations, a descriptive perspective predominates, which, based on the analysis of the leader’s behavior and empirical evidence, is partial and fragmented. A deeper understanding of this phenomenon requires solid anthropology, which explains the concept of the person that underlies it since how the leader conceives the person determines his leadership style and objectives. In this research, we made a literary review of Personalism to have a person’s systematic notion, which contemplates it in all its complexity. On this basis, we propose a model of Comprehensive Personalist Leadership, with an ethical and transcendent sense, in which the leader rethinks his priorities and strives to align the interests of people and the organization towards the common good.En el estudio de la ética del liderazgo en las organizaciones predomina una perspectiva descriptiva, que al fundamentarse en el análisis de las conductas del líder y en la evidencia empírica, es parcial y fragmentada. Una comprensión más profunda de este fenómeno requiere de una antropología sólida, que explique el concepto de persona que subyace en él, pues la manera en que el líder concibe a la persona determina su estilo de liderazgo y sus objetivos. En esta investigación se hace una revisión literaria del Personalismo, para disponer de una noción sistemática de la persona, que la contemple en toda su complejidad. Sobre esta base, se propone un modelo de Liderazgo Personalista Integral, con sentido ético y trascendente, en el que líder se replantea sus prioridades y se esfuerza por alinear los intereses de las personas y de la organización hacia el bien común
