Salud sexual en Chile: una aproximación descriptiva al comportamiento y la satisfacción sexual de los chilenos

Indexación: Web of Science; Scielo.Antecedentes: El año 2006, la Organización Mundial de la Salud definió a la "salud sexual" como un estado de bienestar físico, emocional, mental y social en relación a la propia sexualidad. De este modo, corresponde a un concepto más amplio que la ausencia de malestares, disfunciones o enfermedades, relacionándose con un nivel de bienestar general. Pese a la relevancia del concepto, aún es escasa la evidencia empírica al respecto a nivel local. Objetivos: El artículo analiza el concepto de "salud sexual" a nivel de población general en Chile. Métodos: Se diseñó una muestra probabilística, polietápica y estratificada en el Gran Santiago, encuestándose a 767 personas mayores de 18 años, siguiendo la metodología de autorreporte de hogares. Resultados: El estudio evidencia diferencias según género y edad en la mayor parte de las variables relativas a la satisfacción sexual y a conductas sexuales seguras. Conclusión: Se concluye que los hombres inician su vida sexual más tempranamente, tienen más parejas sexuales y reportan mayor satisfacción sexual que las mujeres, con excepción de la cohorte más joven. Ellas, a su vez, declaran mayores niveles de protección y cuidado de la vida sexual.Background: In 2006, the World Health Organization endorsed the concept of "sexual health" as a state of physical, emotional, mental and social well-being in relation to sexuality. Thus, it corresponds to a broader concept that the absence of disease, dysfunction or infirmity, being related to a general level of well-being. Despite the relevance of the concept, locally, there is still scarce empirical evidence about it. Aims: The article analyses the concept of "sexual health" among the Chilean general population. Methods: In order to achieve this objective, a probabilistic, polyphasic and stratified sample was designed for the province of Santiago, being surveyed 767 people over 18 years, through a self-reported method in their own households. Results: The study shows differences by gender and age in both sexual satisfaction and safe sexual behaviours. Conclusion: It is possible to conclude that men begin their sexual life earlier, have more sexual partners and report higher sexual satisfaction than women, except for the youngest cohort. Women, in turn, report higherhttp://ref.scielo.org/d57vg

Biofertilization of micropropagated Agave tequilana: Effect on plant growth and production of hydrolytic enzymes

Three beneficial bacterial strains [Gluconoacetobacter diazotrophicus (Pal5), the diazotrophs (11B) and Pachaz (008)] and an arbuscular mycorrhizal fungus [Glomus intraradices (AMF)] were evaluated for their ability to enhance plant growth and the production of hydrolytic enzymes in micropropagated Agave tequilana Weber var. Blue. Results show that the growth of the agave plants and the production of hydrolytic enzymes in their roots were influenced by the presence of these microorganisms. AMF + 11B treatment induced the greatest fresh weight, showing significant differences with respect to other combinations. Microscopic analysis showed dense root colonization in the AMF treated plants. Pal 5 treatment produced taller plants, indicating a better plant nitrogen nutrition and possibly phytohormone production by Gluconoacetobacter. Treatment Pachaz 008 presented the highest values of the most important agronomic variables, such as the diameter of the pseudo-stem. On another hand, differential catalytic activities of the enzymes β-glucosidase, cellobiohydrolase and endo-1,4-β-D-glucanase were detected in inoculated roots in comparison to the un-inoculated control . We offer explanations about those results based on nutritional and hormonal relationships between the microorganisms and the agave plantlets, as well as on the microbial mechanism to colonize the agave roots.Key words: Bacterial and mycorrhizal inoculants, Agave plantlets, hydrolytic enzymes

How Integrated Marketing Communications (IMC) works? A theoretical review and an analysis of its main drivers and effects

Since the mid-1990’s, the concept of Integrated Marketing Communications (IMC) has come to the fore and attracted considerable attention in the literature. The main purpose of this paper is twofold: (1) to explore IMC by delimitating its conceptual boundaries and identifying its main dimensions and (2) to develop a whole theoretical model of its antecedents and consequences. To achieve this goal, this study analyzes the conceptual framework around IMC and its dimensions and it presents an extensive literature review. Moreover, a new definition is presented and the main dimensions of the concept are highlighted. A systematic literature review is carried out to identify IMC antecedents and consequences and the research hypotheses are formulated. Following the obtained results, a conceptual model has been developed and the most relevant findings are discussed. Finally, the main academic and managerial implications are described. This model will help academics and marketers to better understand the role that this new marketing paradigm plays within modern management, in identifying the key variables that promote or hinder IMC and the benefits derived from its implementation

Local and Distributed fMRI Changes Induced by 40 Hz Gamma tACS of the Bilateral Dorsolateral Prefrontal Cortex: A Pilot Study

Over the past few years, the possibility of modulating fast brain oscillatory activity in the gamma (γ) band through transcranial alternating current stimulation (tACS) has been discussed in the context of both cognitive enhancement and therapeutic scenarios. However, the effects of tACS targeting regions outside the motor cortex, as well as its spatial specificity, are still unclear. Here, we present a concurrent tACS-fMRI block design study to characterize the impact of 40 Hz tACS applied over the left and right dorsolateral prefrontal cortex (DLPFC) in healthy subjects. Results suggest an increase in blood oxygenation level-dependent (BOLD) activity in the targeted bilateral DLPFCs, as well as in surrounding brain areas affected by stimulation according to biophysical modeling, i.e., the premotor cortex and anterior cingulate cortex (ACC). However, off-target effects were also observed, primarily involving the visual cortices, with further effects on the supplementary motor areas (SMA), left subgenual cingulate, and right superior temporal gyrus. The specificity of 40 Hz tACS over bilateral DLPFC and the possibility for network-level effects should be considered in future studies, especially in the context of recently promoted gamma-induction therapeutic protocols for neurodegenerative disorders. © 2022 Lucia Mencarelli et al

Growth and texture of Spark Plasma Sintered Al2O3 ceramics: a combined analysis of X-rays and Electron Back Scatter Diffraction

Textured alumina ceramics were obtained by Spark Plasma Sintering (SPS) of undoped commercial a-Al2O3 powders. Various parameters (density, grain growth, grain size distribution) of the alumina ceramics, sintered at two typical temperatures 1400{\deg}C and 1700{\deg}C, are investigated. Quantitative textural and structural analysis, carried out using a combination of Electron Back Scattering Diffraction (EBSD) and X-ray diffraction (XRD), are represented in the form of mapping, and pole figures. The mechanical properties of these textured alumina ceramics include high elastic modulus and hardness value with high anisotropic nature, opening the door for a large range of applicationsComment: 16 pages, 6 figures, submitted to J.
