El contexto laboral de las egresadas. Las competencias exigidas
En el entorno actual, la situación del egresado está íntimamente relacionada con su formación para crear valor, esto es, el valor está de manifiesto en la mejora del desempeño de las egresadas en los diversos jardines. La exigencia laboral es considerable y significativa donde los conocimientos especializados en la educación preescolar son necesarios, la planificación y la movilización de saberes de los niños son inevitables, mientras que las formas de comunicación son ineludibles con los padres de familia en un proceso de relación interpersonal. Por otro lado, de acuerdo a los resultados de la encuesta el uso de la tecnología es una exigencia moderada, así como los procesos de gestión institucional. La mirada también está puesta en las exigencias de una práctica profesional eficiente, donde esta se despliega en torno al conocimiento adquirido en la escuela Normal y su capacidad de dar respuesta a las exigencias del entorno
Geometrical Properties of Coupled Oscillators at Synchronization
We study the synchronization of nearest neighbors coupled oscillators in
a ring. We derive an analytic form for the phase difference among neighboring
oscillators which shows the dependency on the periodic boundary conditions. At
synchronization, we find two distinct quantities which characterize four of the
oscillators, two pairs of nearest neighbors, which are at the border of the
clusters before total synchronization occurs. These oscillators are responsible
for the saddle node bifurcation, of which only two of them have a phase-lock of
phase difference equals /2. Using these properties we build a
technique based on geometric properties and numerical observations to arrive to
an exact analytic expression for the coupling strength at full synchronization
and determine the two oscillators that have a phase-lock condition of
/2.Comment: accepted for publication in "Communications in Nonlinear Science and

Train-the-trainers in hand hygiene : a standardized approach to guide education in infection prevention and control
Background
Harmonization in hand hygiene training for infection prevention and control (IPC) professionals is lacking. We describe a standardized approach to training, using a “Train-the-Trainers” (TTT) concept for IPC professionals and assess its impact on hand hygiene knowledge in six countries.Methods
We developed a three-day simulation-based TTT course based on the World Health Organization (WHO) Multimodal Hand Hygiene Improvement Strategy. To evaluate its impact, we have performed a pre-and post-course knowledge questionnaire. The Wilcoxon signed-rank test was used to compare the results before and after training.Results
Between June 2016 and January 2018 we conducted seven TTT courses in six countries: Iran, Malaysia, Mexico, South Africa, Spain and Thailand. A total of 305 IPC professionals completed the programme. Participants included nurses (n = 196; 64.2%), physicians (n = 53; 17.3%) and other health professionals (n = 56; 18.3%). In total, participants from more than 20 countries were trained. A significant (p < 0.05) improvement in knowledge between the pre- and post-TTT training phases was observed in all countries. Puebla (Mexico) had the highest improvement (22.3%; p < 0.001), followed by Malaysia (21.2%; p < 0.001), Jalisco (Mexico; 20.2%; p < 0.001), Thailand (18.8%; p < 0.001), South Africa (18.3%; p < 0.001), Iran (17.5%; p < 0.001) and Spain (9.7%; p = 0.047). Spain had the highest overall test scores, while Thailand had the lowest pre- and post-scores. Positive aspects reported included: unique learning environment, sharing experiences, hands-on practices on a secure environment and networking among IPC professionals. Sustainability was assessed through follow-up evaluations conducted in three original TTT course sites in Mexico (Jalisco and Puebla) and in Spain: improvement was sustained in the last follow-up phase when assessed 5 months, 1 year and 2 years after the first TTT course, respectively.Conclusions
The TTT in hand hygiene model proved to be effective in enhancing participant’s knowledge, sharing experiences and networking. IPC professionals can use this reference training method worldwide to further disseminate knowledge to other health care workers.peer-reviewe
Molecular analysis of hepatitis B virus "a" determinant in asymptomatic and symptomatic Mexican carriers
BACKGROUND: Hepatitis B virus (HBV) is a small DNA-containing virus with 4 genes, C, S, X and P. The S gene codes for the surface antigen (HBsAg), which contains the "a" determinant, the main region for induction of a protective humoral immune response. To compare the genotype and sequence of the "a" determinant between strains isolated from asymptomatic and symptomatic Mexican HBV carriers. RESULTS: 21 asymptomatic (blood donors) and 12 symptomatic (with clinical signs and with >1 year lamivudine treatment) HBV carriers were studied; all patients were positive for the HBsAg in serum. Viral load, genotypes, and subtypes were determined in plasma. A fragment of the S gene including the "a" determinant was PCR amplified and sequenced to determine genotype, subtype and to identify mutations. Mean viral load was 0.7965 × 10(4 )copies/ml in asymptomatic carriers and 2.73 × 10(6 )copies/ml in symptomatic patients. Genotypes H, C, and F were identified in asymptomatic individuals; whereas H was dominant in symptomatic patients. A fragment of 279 bp containing the "a" determinant was amplified from all 33 carriers and sequences aligned with S gene sequences in the GenBank. Mutations identified were Y100N, T126I, Q129H and N146K in the asymptomatic group, and F93I and A128V in the symptomatic group. CONCLUSION: Differences in genotype and in mutations in the "a" determinant were found between strains from asymptomatic and symptomatic HBV Mexican carriers
Los saberes docentes: un análisis desde la situación docente en la escuela normal
En un entorno en constante cambio social, la formulación del éxito de las Escuelas Normales es la creación y reflexión del conocimiento. Estos nuevos saberes y conocimientos han de ser compartidos y diseminados a través de la organización e incorporados en los procesos de enseñanza, es necesario señalar la importancia de rescatar y dar significado a los saberes de los docentes y como éstos se construyen en el contexto de la práctica, como conjunto de concepciones disciplinares y meta disciplinares en los diferentes momentos del proceso de la intervención. Cada día en el salón de clases ocurren una diversidad de acontecimientos o sucesos que nos llevan a reconstruir y revalorar la práctica y los saberes que se inmiscuyen de la misma, como espejos que se reflejan, pero con mirada abierta y reflexiva para retomar y reestructurar nuestra acción, con la preparación anticipada de los contenidos, la planeación, y los saberes que se involucran en el conocimiento profesional de los docentes, los saberes se van construyendo en la práctica y centrando de manera significativa en el aprendizaje de los alumnos. En este sentido el saber didáctico que se aplica en situaciones acorde a las exigencias y desafíos cobra relevancia en la educación actual
GluN2A NMDA Receptor Enhancement Improves Brain Oscillations, Synchrony, and Cognitive Functions in Dravet Syndrome and Alzheimer's Disease Models.
NMDA receptors (NMDARs) play subunit-specific roles in synaptic function and are implicated in neuropsychiatric and neurodegenerative disorders. However, the in vivo consequences and therapeutic potential of pharmacologically enhancing NMDAR function via allosteric modulation are largely unknown. We examine the in vivo effects of GNE-0723, a positive allosteric modulator of GluN2A-subunit-containing NMDARs, on brain network and cognitive functions in mouse models of Dravet syndrome (DS) and Alzheimer's disease (AD). GNE-0723 use dependently potentiates synaptic NMDA receptor currents and reduces brain oscillation power with a predominant effect on low-frequency (12-20 Hz) oscillations. Interestingly, DS and AD mouse models display aberrant low-frequency oscillatory power that is tightly correlated with network hypersynchrony. GNE-0723 treatment reduces aberrant low-frequency oscillations and epileptiform discharges and improves cognitive functions in DS and AD mouse models. GluN2A-subunit-containing NMDAR enhancers may have therapeutic benefits in brain disorders with network hypersynchrony and cognitive impairments
Vivencias de acoso escolar en jóvenes: análisis y reflexión desde el psicoanálisis
Articulo especializadoEste artículo presenta el análisis de las vivencias de un grupo de jóvenes que han sido
objeto de acoso escolar, a partir de la percepción de sí mismos, su historia familiar
y su contexto socio-escolar, desde una perspectiva psicoanalítica. Participaron seis
estudiantes del nivel medio superior a través de una entrevista semiestructurada y el
Test de Apercepción Temática. Los hallazgos indican que estos jóvenes, al ocupar un
lugar de desvalorización, complacencia y vulnerabilidad en la familia, son más proclives
a mantener esa condición ante los pares escolares y las relaciones de noviazgo,
se callan las agresiones recibidas y prevalece una la ley del silencio
