아주 옛날 (Once Upon a Time): Koreanovelas and the Galleon Trade of the Digital Age

The evident proliferation of Korean television programs in the Philippines manifests a modern form of trade between the two countries. Though there are latent negativities, this trade brings forth a lot of positive effects between the nations involved, specifically in the modern television industry of the latter. Through the three-step copycat-piggyback-leapfrog innovation, export-quality Koreanovelas facilitate product creativity that can increase not only the quantity, but more importantly the quality, of locally-produced television goods. The presence and proliferation of Koreanovelas also challenges the local industry as it promotes competition for patronization in limited television timeslots. This competition works side-by-side with creativity. Scarce resources with desirable incentives push television stations to offer only programs that are good enough to be consumed in another country, products that are most likely of superior quality. Finally, Koreanovelas improve employment especially in the Philippine-end of the barter. The drive to produce better programs brought about by heightened creativity and competition will increase production. This, in turn, will cause television stations to employ more and better workers, improving workers and the television industry as a whole

The Puzzling Stability of Monatomic Gold Wires

We have examined theoretically the spontaneous thinning process of tip-suspended nanowires, and subsequently studied the structure and stability of the monatomic gold wires recently observed by Transmission Electron Microscopy (TEM). The methods used include thermodynamics, classical many-body force simulations, Local Density (LDA) and Generalized Gradient (GGA) electronic structure calculations as well as ab-initio simulations including the two tips. The wire thinning is well explained in terms of a thermodynamic tip suction driving migration of surface atoms from the wire to the tips. For the same reason the monatomic wire becomes progressively stretched. Surprisingly, however, all calculations so far indicate that the stretched monatomic gold wire should be unstable against breaking, contrary to the apparent experimental stability. The possible reasons for the observed stability are discussed.Comment: 4 figure

Effect of HDI-Modified GO on the Thermoelectric Performance of Poly(3,4-ethylenedioxythiophene):Poly(Styrenesulfonate) Nanocomposite Films

Composite films based on conducting polymers and carbon nanomaterials have attracted much attention for applications in various devices, such as chemical sensors, light-emitting diodes (LEDs), organic solar cells (OSCs), among others. Graphene oxide (GO) is an ideal filler for polymeric matrices due to its unique properties. However, GO needs to be functionalized to improve its solubility in common solvents and enable the processing by low-cost solution deposition methods. In this work, hexamethylene diisocyanate (HDI)-modified GO and its nanocomposites with poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) were developed, and their morphology, thermal, electrical, thermoelectrical and mechanical performance were characterized. The influence of the HDI functionalization degree and concentration on the nanocomposite properties were assessed. The HDI-GO increased the crystallinity, lamella stacking and interchain coupling of PEDOT:PSS chains. A strong improvement in electrical conductivity, thermal stability, Young's modulus and tensile strength was found, showing an optimum combination at 2 wt% loading. Drop and spin casting techniques were applied onto different substrates, and the results from deposition tests were analyzed by atomic force microscopy (AFM) and UV-vis spectroscopy. A number of parameters influencing the depositions process, namely solvent nature, sonication conditions and ozone plasma treatment, have been explored. This study paves the way for further research on conducting polymer/modified GO nanocomposites to optimize their composition and properties (i.e., transparency) for use in devices such as OSCs

Importancia de la tetanalgesia en la realización de técnicas dolorosas en el recién nacido

Cartel presentado en la Segunda Conferencia Internacional de Comunicación en Salud, celebrada el 23 de octubre de 2015 en la Universidad Carlos III de MadridIntroducción: Hoy en día, es conocido que las estructuras que transmiten el dolor están totalmente desarrolladas antes del nacimiento, al contrario de lo que se pensaba hasta hace no mas de una década. Así pues, hay numerosos estudios que demuestran que los recién nacidos son capaces de sentir dolor e incluso tener una respuesta mas exagerado con respecto a niños de más edad. Con el término tetanalgesia se entiende el efecto analgésico producido en los neonatos cuando están siendo amamantados. Objetivos: Conocer los beneficios del uso de la tetanalgesia en los recién nacidos cuando son sometidos a técnicas dolorosas. Metodología: Estudio observacional sobre datos publicados. Se realiza un revisión bibliográfica con las bases de datos Pubmed, CINAHL, Cochrane y google académico usando las palabras claves: newborn, analgesia, breast feeding, pain. Resultados: Aunque el mecanismo analgésico de la lactancia materna no es bien conocido se cree que se debe a la relación de varios factores tales como el contacto piel con piel, el componente hormonal, el tacto y el gusto azucarado entre otros. La leche materna contiene mayor cantidad de triptófano que la artificial, siendo este un precursor de la melatonina que aumenta la concentración de las endorfinas beta. Según estudios llevados a cabo se ha observado que el amamantamiento es el procedimento mas efectivo frente a otras técnicas analgésicas, mostrando una reducción del tiempo de llanto del 98% en la realizacion de la prueba del talon. Una revisión de la Cochrane concluye que el amamantamiento en la realización de técnicas dolorosas se asocia a menor cambios en la frecuencia cardíaca y en la duración del llanto. Conclusiones: El uso de la lactancia materna en procedimientos dolorosos es el método no farmacológico más eficaz

The role of dieting, happiness with appearance, self-esteem, and bullying in the relationship between mental health and body-mass index among UK adolescents: a longitudinal analysis of the Millennium Cohort Study.

BACKGROUND: Mental illness and obesity are among the biggest challenges to population health, they are linked, and may be modifiable during adolescence. We aimed to determine intervening pathways between mental health and BMI z-score symptoms across adolescence. METHODS: In this longitudinal cohort study, we used path models to examine self-reported dieting, happiness with appearance, self-esteem and bullying at 14 years as potential mediators of the cross-lagged relationship between mental health (via the Strengths and Difficulties Questionnaire) and Body Mass Index (BMI) z-score at 11 and 17 years by sex in the UK Millennium Cohort Study, a prospective cohort study of 18,818 children born in the UK between September 1st, 2000, and January 31st, 2002. Full, incomplete data on all singleton children still participating in the study by age 11 years were analysed in GSEM via maximum likelihood estimation (N = 12,450). FINDINGS: We found happiness with appearance and self-esteem, but not dieting or bullying, mediated the relationship between BMI age 11 and mental health age 17. Each increase in BMI z-score at 11 years was associated with 0.12 increase for boys and a 0.19 increase for girls in scores of unhappiness with appearance (boys: b 0.12, 95% C.I.; girls b 0.19, C.I. 0.14 to 0.23) and a 16% increase for boys and a 22% increase for girls in odds of low self-esteem (boys OR 1.16, 95% C.I. 1.07 to 1.26; girls: OR 1.22, 95% C.I. 1.15 to 1.30) at 14 years. In turn, for both boys and girls, being unhappy with appearance and low self-esteem at 14 years were associated with a greater likelihood of emotional and externalizing symptoms at 17 years. INTERPRETATION: Early prevention strategies to encourage healthy physical and mental development of children need to focus on the promotion of positive body-mage and self-esteem.

Benchmarking a MOS-based algorithm on the BBOB-2010 noiseless function testbed

In this contribution, a hybrid algorithm combining Differential Evolution and IPOP-CMA-ES is presented and benchmarked on the BBOB 2010 noiseless testbed. The hybrid algorithm has been constructed within the Multiple Offspring Sampling framework, which allows the seamless combination of multiple metaheuristics in a dynamic algorithm capable of adjusting the participation of each of the composing algorithms according to their current performance. The experimental results show a robust behavior of the algorithm and a good scalability as the dimensionality increases
