Association of Infant Frontal EEG Asymmetry with prenatal maternal pregnancy-related anxiety
High levels of anxiety during pregnancy are associated with behaviour problems and increased risk of health difficulties in the offspring. Understanding how prenatal anxiety affects brain structure and function may help clarify its potential implications in neurodevelopment. Frontal electroencephalographic (EEG) alpha asymmetry has been used as an index for differences in approach/withdrawal tendencies and negative affect after birth. The data for this master thesis was collected from a sub-sample (n=105) of the FinnBrain Birth Cohort Study. The aim was to investigate the associations between frontal EEG asymmetry in newborns and prenatal maternal anxiety levels, measured with the Pregnancy-Related Anxiety Questionnaire (PRAQ-R2), during pregnancy. No significant associations were found between asymmetry scores and PRAQ-R2. Since this questionnaire measures only pregnancy-related anxiety, future studies should investigate potential effects of maternal prenatal anxiety in newborns considering more general aspects of maternal anxiety
Novalis, Die Christenheit oder Europa. Una lectura a la altura del tiempo
Die Christenheit oder Europa(1799) is a fundamental document in German Romanticism, a provocative essay in which Novalis calls for the restoration of a mystical Europe. The aim of this article is firstly to review the obscurantist legend that has dogged Novalis’ minor work since its origins, before embarking on a new reading of it and attempting to measure the objective importance of its propositions for the present. Die Christenheit oder Europa(1799) es un documento fundacional del Romanticismo alemán, un provocador ensayo en el que Novalis desea la restauración de una Europa mística. El objeto del presente artículo será, en primer lugar, revisar la leyenda oscurantista que arrastra desde sus orígenes el opúsculo de Novalis, para, a continuación, emprender una nueva lectura del mismo intentando medir la importancia objetiva de sus propuestas en el presente.
A discrete model of competing species sharing a parasite
In this work we develop a discrete model of competing species affected by a
common parasite. We analyze the influence of the fast development of the shared
disease on the community dynamics. The model is presented under the form of a
two time scales discrete system with four variables. Thus, it becomes
analytically tractable with the help of the appropriate reduction method. The
2-dimensional reduced system, that has the same the asymptotic behaviour of the
full model, is a generalization of the Leslie-Gower competition model. It has
the unfrequent property in this kind of models of including multiple
equilibrium attractors of mixed type. The analysis of the reduced system shows
that parasites can completely alter the outcome of competition depending on the
parasite's basic reproductive number R0. In some cases, initial conditions
decide among several exclusion or coexistence scenarios
Discrete-time staged progression epidemic models
In the Staged Progression (SP) epidemic models, infected individuals are
classified into a suitable number of states. The goal of these models is to
describe as closely as possible the effect of differences in infectiousness
exhibited by individuals going through the different stages. The main objective
of this work is to study, from the methodological point of view, the behavior
of solutions of the discrete time SP models without reinfection and with a
general incidence function. Besides calculating , we find
bounds for the epidemic final size, characterize the asymptotic behavior of the
infected classes, give results about the final monotonicity of the infected
classes, and obtain results regarding the initial dynamics of the prevalence of
the disease. Moreover, we incorporate into the model the probability
distribution of the number of contacts in order to make the model amenable to
study its effect in the dynamics of the disease
Discrete epidemic models with two time scales
The main aim of the work is to present a general class of two time scales
discrete-time epidemic models. In the proposed framework the disease dynamics
is considered to act on a slower time scale than a second different process
that could represent movements between spatial locations, changes of individual
activities or behaviours, or others. To include a sufficiently general disease
model, we first build up from first principles a discrete-time
Susceptible-Exposed-Infectious-Recovered-Susceptible (SEIRS) model and
characterize the eradication or endemicity of the disease with the help of its
basic reproduction number R0. Then, we propose a general full model that
includes sequentially the two processes at different time scales, and proceed
to its analysis through a reduced model. The basic reproduction number R0 of
the reduced system gives a good approximation of the R0 of the full model since
it serves at analyzing its asymptotic behaviour. As an illustration of the
proposed general framework, it is shown that there exist conditions under which
a locally endemic disease, considering isolated patches in a metapopulation,
can be eradicated globally by establishing the appropriate movements between
patches
Emotional intelligence in the personality of the troop military that works in the air force group 8 in Callao, 2018
La inteligencia emocional es una capacidad que desarrollan las personas para relacionarse con
los demás, de conectarse con emociones, de gestionarlas, de auto-motivarlas, de saber controlar
y frenar los impulsos, de vencer frustraciones, Esto se vinculan directamente con la personalidad
rasgos y caracteres sumados a los factores personales, familiares y laborales entre otras. El
objetivo es determinar la influencia de la inteligencia emocional en la personalidad del militar de
tropa. El estudio fue descriptivo de corte transversal, no experimental. La población estuvo
conformada por 150 militares de tropa; Se utilizaron dos escalas: de inteligencia emocional y
personalidad respetando las consideraciones éticas. Los resultados evidencian que existe
influencia de la inteligencia emocional en la personalidad; con respecto a la Inteligencia emocional
el 22 % no presentan optimismo, 6% no maneja control de impulsos y tolerancia al estrés, 11 %
no tienen capacidad para solucionar problemas, el 22 % no se adaptan al medio en el que se
encuentran y el 39 % no son asertivos (interpersonal y intrapersonal). En relación a la personalidad
34% poseen dominancia, 11% no poseen tolerancia, 22% no tienen tenacidad, 100% no tiene
estabilidad emocional, 11% no tienen creatividad y 22% poseen distorsión. En conclusión, existe
influencia entre la inteligencia emocional y personalidad; sin embargo los rasgos y características
individuales de cada persona pueden variar en el manejo de emociones y fortalecer las relaciones
personales y transpersonales con los demás en el ámbito laboral
