The influence of physical attractiveness and gender on perceived competence of sportscasters

The media tends to represent female athletes as women first and athletes second (Koivula, 1 999). The present study investigated whether this same trend was present for female sportscasters, using a self-presentational framework. Self-presentation is the process by which people try to control how others see them (Leary, 1995). One factor that may influence the type of image they try to project is their roles held in society, including gender roles. The gender roles for a man include dominance, assertiveness, and masculinity, while the gender roles for a woman include nurturer, femininity, and attractiveness (Deaux & Major, 1 987). By contrast, sports broadcasters are expected to be knowledgeable, assertive, and competent. Research suggests that female sports broadcasters are seen as less competent and less persuasive than male sports broadcasters (Mitrook & Dorr, 2001; Ordman & Zillmann, 1994, Toro, 2005). One reason for this difference may be that the gender roles for a man are much more similar to those of a sportscaster, compared to those of a woman. Thus, there may be a conflict between the two roles for women. The present study investigated whether the gender and perceived attractiveness of sportscasters influenced the audience's perceptions of the level of competence that a sportscaster demonstrates. Two hundred and four male (n =75) and female (n =129) undergraduate students were recruited from a southern Ontario university to participate in the study. The average age of the male participants was 21 .23 years {SD =1 .60), and the average age for female participants was 20.67 years {SD = 1 .31). The age range for all participants was from 19 to 30 years {M = 20.87 years, SD = 1 .45). Af^er providing informed consent, participants randomly received one of four possible questionnaire packages. The participants answered the demographic questionnaire, and then proceeded to view the picture and read the script of a sports newscast. Next, based on the picture and script, the participants answered the competence questionnaire, assessing the general, sport specific, and overall competence of the sportscaster. Once participants had finished, they returned the package to the researcher and were thanked for their time. Data was analyzed using an ANOVA to determine if general sport competence differs with respect to gender and attractiveness of the sportscaster. Overall, the ANOVA was non-significant (p > .05), indicating no differences on the dependent variable based on gender (F (3, 194) = .631, p = .426), attractiveness (F (3, 194) = .070, p = .791), or the interaction of the two {F (3, 194) = .043,/? = .836). Although none of the study hypotheses were supported, the study provided some insight to the perceived competence of female sportscasters. It is possible that female sportscasters are now seen as competent in the area of sports. Sample characteristics could also have influenced these results; the participants in the current study were primarily physical education and kinesiology students, who had experience participating in physical activity with both men and women. Future research should investigate this issue further by using a video sportscast. It is possible that delivery characteristics such as voice quality or eye contact may also impact perceptions of sportscasters.

Lumbar-sacral pedicle screw insertion with preoperative CT-based navigation

Objectif: Nous avons effectué une étude chez 135 patients ayant subis une chirurgie lombo-sacrée avec vissage pédiculaire sous navigation par tomographie axiale. Nous avons évalué la précision des vis pédiculaires et les résultats cliniques. Méthodes: Cette étude comporte 44 hommes et 91 femmes (âge moyen=61, intervalle 24-90 ans). Les diamètres, longueurs et trajectoires des 836 vis ont été planifiés en préopératoire avec un système de navigation (SNN, Surgical Navigation Network, Mississauga). Les patients ont subi une fusion lombaire (55), lombo-sacrée (73) et thoraco-lombo-sacrée (7). La perforation pédiculaire, la longueur des vis et les spondylolisthesis sont évalués par tomographies axiales postopératoires. Le niveau de douleur est mesuré par autoévaluations, échelles visuelles analogues et questionnaires (Oswestry et SF-36). La fusion osseuse a été évaluée par l’examen des radiographies postopératoires. Résultats: Une perforation des pédicules est présente pour 49/836 (5.9%) des vis (2.4% latéral, 1.7% inférieur, 1.1% supérieur, 0.7% médial). Les erreurs ont été mineures (0.1-2mm, 46/49) ou intermédiaires (2.1 - 4mm, 3/49 en latéral). Il y a aucune erreur majeure (≥ 4.1mm). Certaines vis ont été jugées trop longues (66/836, 8%). Le temps moyen pour insérer une vis en navigation a été de 19.1 minutes de l΄application au retrait du cadre de référence. Un an postopératoire on note une amélioration de la douleur des jambes et lombaire de 72% et 48% en moyenne respectivement. L’amélioration reste stable après 2 ans. La dégénérescence radiologique au dessus et sous la fusion a été retrouvée chez 44 patients (33%) and 3 patients respectivement (2%). Elle est survenue en moyenne 22.2 ± 2.6 mois après la chirurgie. Les fusions se terminant à L2 ont été associées à plus de dégénération (14/25, 56%). Conclusion: La navigation spinale basée sur des images tomographiques préopératoires est une technique sécuritaire et précise. Elle donne de bons résultats à court terme justifiant l’investissement de temps chirurgical. La dégénérescence segmentaire peut avoir un impact négatif sur les résultats radiologique et cliniques.

Studies on the Cure Characteristics of Elastomer Blends

Blends of natural rubber (NR) with styrene-butadiene rubber (SBR), polybutadiene rubber (BR), ethylene-propylene terpolymer (EPDM) and acrylonitrile-butadiene rubber (NBR) were vulcanised using an efficient vulcanisation (EV) system and a semi-EV system. Compatible blends show a definite pattern of curing whereas the incompatible blends show no such pattern.

Photoacoustic studies on multilayer dielectric coatings

Non-destructive testing d multilayer dielectric coatings (SiO2/TiO2 structure) has been carried out using the photoacoustic technique. This technique makes use d a 10 mW He-Ne laser, a photoacoustic cell and a lock-in amplifier. The chopped He-Ne laser beam is allowed to fall on the sample placed in a photoacoustic cell. The acoustic signals thus generated are detected using a microphone and the resulting output is processed by a lock-in amplifier. The amplitude and phase of the signals were measured as a function of the chopping frequency. Striking step-like variations are observed in me phase against frequency plot which dearly reveals the different layers present in the multilayer structure.

Synthesis, characterization and kinetic studies on complex formed between amantadine hydrochloride and sodium molybdate at physiological pH

The title reaction was undertaken to establish the interaction between amantadine and molybdate at physiological pH. Identical FTIR spectra, TG-DTA curves and CHN data of the complexes formed from three solutions at pH 1.5, 7.4 and 8.0 indicate that the same complex was formed at all the three pHs. The FTIR spectrum shows shift in peaks corresponding to primary amino group of the drug due to coordination to molybdate. An octahedral geometry is assigned to the complex. The kinetics of the complexation has been studied at low concentrations of the reactants using UV-visible spectrophotometry. At pH 7.4, the initial rate varies linearly with [molybdate]. A plot of initial rate versus [drug] is linear passing through origin. These results indicate that the drug and molybdate react at pH 7.4 even at low concentrations. At pH 1.5, the rate increases linearly with increase in [drug] but decreases with [molybdate]. The effect of pH and ionic strength on the rate of the reaction has also been studied. A suitable mechanism has been proposed for the reaction. Reaction between the drug and molybdate even at low concentrations and the fact that the amino group of amantadine required to be free for its function as antiviral, is bound to molybdate in the complex suggests that simultaneous administration of the drug and molybdate supplements should be avoided.

Diseño de Plan Exportador para Corpoempack Ltda.

Debido a la globalización acelerada que esta experimentando el mundo, la economía y los mercados mundiales están creciendo cada día más y más, esto hace que pequeñas empresas tenga que crecer a la velocidad que el mundo lo pide, este es el caso de Corpoempack Ltda., una PyME diseñadora y productora de artículos de expresión social como tarjetas de felicitación, amor, apoyo, papel regalo, cuadernos, agendas, carpetas entre otros, que en vista de que el mercado nacional se estaba quedando pequeño frente a tantos oferentes vieron la necesidad de ampliar sus horizontes intentando conquistar mercados externos comenzando a exportar a Ecuador y otros países vecinos, pero no siendo esto suficiente se propusieron penetrar otros continentes por eso la razón de esta investigación tomando 2 posibles países: México como puerta de entrada a Norteamérica, y España como la posibilidad de ingreso a Europa. Se realizo un estudio detallado de los 2 posibles países viendo las ventajas y desventajas para exportar allá y a su vez abrir una tienda de expresión social con productos exclusivos Corpoempack. Como resultado se obtuvo que la mejor opción seria exportar a España por facilidades en acuerdos comerciales, el tamaño de las colonias latinas y la fuerza que tienen en el mercado y por ultimo la competencia que existe en este campo como almacenes exclusivos de expresión social es baja, así que seria una gran oportunidad de darle a los españoles productos innovadores y netamente colombianos. Proyectando el negocio a 5 años, considerando que las condiciones del mercado se mantienen o mejoran, será un negocio muy rentable y con miras a un rápido crecimiento, claro esta teniendo en cuenta las mejoras tanto organizacional como en estructura en la casa matriz Colombia ya que hay varios puntos débiles que reforzar en clima y administración.

Classification of textures seen from different distances and under varying illumination direction

Changes in the angle of illumination incident upon a 3D surface texture can significantly alter its appearance, implying variations in the image texture. These texture variations produce displacements of class members in the feature space, increasing the failure rates of texture classifiers. To avoid this problem, a model-based texture recognition system which classifies textures seen from different distances and under different illumination directions is presented in this paper. The system works on the basis of a surface model obtained by means of 4-source colour photometric stereo, used to generate 2D image textures under different illumination directions. The recognition system combines coocurrence matrices for feature extraction with a Nearest Neighbour classifier. Moreover, the recognition allows one to guess the approximate direction of the illumination used to capture the test image

Situación nutricional de la infancia en Bogotá D.C. : evolución de resultados del Sistema de Vigilancia Alimentaria y Nutricional (SISVAN) 1998-2009

El estado nutricional es un indicador de calidad de vida de los individuos; la malnutrición se ha constituido en una problemática de la población infantil de países en vía de desarrollo cuya reducción se ha incluido en los objetivos del Milenio; para su abordaje, Colombia implementó el Sistema de Vigilancia Epidemiológica Alimentaria y Nutricional –SISVAN- que desde 1998, ha recopilado información del estado nutricional de niños y niñas. Metodología: Estudio descriptivo longitudinal con un análisis evolutivo (pruebas ANOVA y Bonferoni) de la malnutrición en infantes de Bogotá, con base en los reportes del SISVAN desde 1998 al 2009. La clasificación nutricional se determinó mediante gráficas de la NCHS. Empleamos software SPSS 15. Resultados: 1’836.903 registros totales depurados (895638 niñas y 941265 niños), pertenecientes a 20 localidades de Bogotá. La prevalencia de malnutrición encontrada varía según el indicador antropométrico utilizado (Peso/Edad, Talla/Edad y Peso/Talla), así: desnutrición global varía de 2.6%(1998) a 2.8%(2009); de 1.5%(1998) a 1.6%(2009) para sobrepeso y para obesidad 0.8% según el indicador Peso/Edad para ambos géneros. Indicador Talla/Edad: prevalencias de 5.1%(1998) a 4.8%(2009) para desnutrición crónica y retraso de crecimiento de 11.7%(1998) a 11.1% (2009). Indicador Peso/Talla se encuentra: 12.7%(1998) a 12.6%(2009) para desnutrición aguda, 4.9%(1998) a 4.2%(2009) para sobrepeso y para obesidad de 4.8%(1998) a 4.0%(2009). Conclusiones: Existen diferencias significativas entre las prevalencias de desnutrición, sobrepeso y obesidad durante los años de reporte del SISVAN, observándose una tendencia al decrecimiento en obesidad, desnutrición aguda y crónica, y a un comportamiento sin variaciones para sobrepeso.
