El impacto de las normas y de la ideología sobre el procesamiento emocional, motivacional y cognitivo del comportamiento político de las elites de poder y la ciudadanía de Córdoba. Norms and ideologies impact on the emotional, motivational and cognitive processesing of power elite and citizen political behavior in Cordoba.

El presente estudio pretende arribar a la construcción de un modelo explicativo del comportamiento político a partir de la contribución que los marcos sociales (norma sociales, normas de ciudadanía, ideología, confianza política) y sociocognitivos (inteligencia afectiva, interés político, eficacia política, conocimiento político, sentimiento de comunidad) mostraron, en términos de relaciones entre las variables, sobre el mismo. Nuestra atención se centra no sólo al comportamiento político de la ciudadanía -que es donde se desarrollaron la mayor parte de los estudios-, sino a las elites de poder constitutivas del sistema político (jueces, legisladores provinciales y representantes de instituciones del gobierno y de organismos no gubernamentales). Asimismo, pretende establecer las diferencias que puedan evidenciarse en torno a la relación de estas variables con el comportamiento político entre los distintos colectivos estudiados en el ámbito de la ciudad de Córdoba. Para ello se realizara una primera etapa de estudio instrumental, con el objeto de analizar las propiedades psicométricas de los instrumentos a utilizar en la operacionalización de las variables. Para ello se tomara una muestra accidental de 250 personas entre 18 y 65 años de edad. Posteriormente, se realizarán dos etapas de estudio ex post facto, con la finalidad de construir los modelos planteados. En la primera de ellas, se trabajará con una muestra accidental de 100 representantes de los grupos de poder estudiados y en la segunda con una muestra probabilística de 500 ciudadanos cordobeses entre 18 y 65 años de edad.

Synchronous reproduction may facilitate introgression in a hybrid mussel (Mytilus) population

Mussel populations on the Irish Atlantic coast comprise an interbreeding mixture of the blue mussel, Mytilus edulis (L.) and the Mediterranean mussel, Mytilus galloprovincialis (Lmk.). The occurrence of hybrid genotypes varies between sites but can be as high 80%. This study compares the reproductive cycle of M. edulis, M. galloprovincialis and their hybrids to determine if the extensive hybridisation observed at Irish Atlantic coast sites is linked to spawning synchrony between the two taxa. Mussels (40-45 mm size class) were collected monthly from a sheltered shore in Galway Bay from January to December 2005. Two major spawning events (March- June and September-October) were observed and gametogenesis took place throughout the year. The spawning cycles of the three taxa were largely overlapping. Small differences were observed in the timing of peak spawning which occurred in March and October in M. galloprovincialis and in May-June and September in M.edulis. Spawning of hybrid individuals was intermediate between the parental genotypes. Fecundity was slightly higher in M. galloprovincialis females compared to the other taxa (up to 30% difference, p<0.05). This apparent advantage is not shared by the sexes and is likely being offset by high numbers of hybrid genotypes releasing gametes during peak spawning of M. galloprovincialis. There was no evidence for increased mortality in hybrid males; sex ratios did not deviate from the 1:1 ratio. The results show that in this region of the hybrid zone the timing of reproduction does not present a barrier to gene flow between M. edulis and M. galloprovincialis. Nonetheless, small differences in the timing of peak spawning may increase the likelihood of conspecific fertilisation at certain times of the year. Hybrids outnumber the parental genotypes, undergo complete gametogenesis and show no evidence of depressed fitness (i.e. hybrids are reproductively competent suggesting a high degree of introgression.

Proposal Intensity Adequacy of Expiratory Effort and Heart Rate Behavior During the Valsalva Maneuver in Preadolescents

Background: When performing the Valsalva maneuver (VM), adults and preadolescents produce the same expiratory resistance values. Objective: To analyze heart rate (HR) in preadolescents performing VM, and propose a new method for selecting expiratory resistance. Method: The maximal expiratory pressure (MEP) was measured in 45 sedentary children aged 9-12 years who subsequently performed VM for 20 s using an expiratory pressure of 60%, 70%, or 80% of MEP. HR was measured before, during, and after VM. These procedures were repeated 30 days later, and the data collected in the sessions (E1, E2) were analyzed and compared in periods before, during (0-10 and 10-20 s), and after VM using nonparametric tests. Results: All 45 participants adequately performed VM in E1 and E2 at 60% of MEP. However, only 38 (84.4%) and 25 (55.5%) of the participants performed the maneuver at 70% and 80% of MEP, respectively. The HR delta measured during 0-10 s and 10-20 s significantly increased as the expiratory effort increased, indicating an effective cardiac autonomic response during VM. However, our findings suggest the VM should not be performed at these intensities. Conclusion: HR increased with all effort intensities tested during VM. However, 60% of MEP was the only level of expiratory resistance that all participants could use to perform VM. Therefore, 60% of MEP may be the optimal expiratory resistance that should be used in clinical practice.

Hypertensives' Knowledge About High-Sodium Foods and Their Behavior

Abstract Background: In Brazil, the prevalence of systemic arterial hypertension (SAH) is approximately 30% of the total population. In 2010, SAH was the cause of death of about 9.4 million people worldwide. A healthy dietary pattern is important to maintain proper blood pressure levels and, consequently, disease control. Objectives: To describe the knowledge and practices of hypertensive patients cared for at a public hypertension outpatient clinic, and its relationship with high-sodium food. Methods: We applied a questionnaire to patients with questions related to sociodemographics, dietary pattern, frequency of ingestion of certain foods, and knowledge about their own disease. Results: We studied 221 patients, 56.1% of whom were women, and 53.8% had only elementary education. Their mean age was 57.7 ±13.5 years, and 75.6% of them reported having high blood pressure, and 11.3%, diabetes mellitus. Regarding dietary pattern, 62% used ready-to-use seasonings, but 94.1% reported not adding extra salt to their ready meals. Regarding patients' knowledge about high-sodium foods and SAH, only 8 patients had 100% of right answers, 37 patients had 73.8%, and 42 patients, 57% of right answers. Conclusion: Knowledge about SAH prevention and high-sodium foods was insufficient. Based on this study's findings, more effective educational strategies targeted at this population can be developed.
