The exercise leader's gender and physique salience : effects on self-presentational concerns in an exercise context

Self-presentation is the process by which individuals attempt to monitor and control how others perceive and evaluate them (Leary, 1992; Leary & Kowalski, 1990). Self-presentational concerns have been shown to influence a number of exercise-related behaviours, cognitions, and affective responses to exercise (e.g., social anxiety). Social anxiety occurs when an individual wants to create a specific impression on others, but is unsure (s)he will be successful (Leary & Kowalski, 1995). Social physique anxiety (SPA) is a specific form of social anxiety related the evaluation of one's body (Hart, Leary, & Rejeski, 1989). Both social anxiety and SPA may act as deterrents to exercise (Lantz, Hardy, & Ainsworth, 1997; Leary, 1992), so it is important to examine factors that may influence social anxiety and SPA; one such factor is self-presentational efficacy (SPE). SPE is one's confidence in successfully making desired impressions on others (Leary & Atherton, 1986) and has been associated with social anxiety and SPA (Leary & Kowalski, 1995; Gammage, Martin Ginis, & Hall, 2004). Several aspects of the exercise environment, such as the presence of mirrors, clothing, and the exercise leader or other participant characteristics, may be manipulated to influence self-presentational concerns (e.g., Gammage, Martin Ginis et aI., 2004; Martin & Fox, 2001; Martin Ginis, Prapavessis, & Haase, 2005). Given that the exercise leader has been recognized as one of the most important influences in the group exercise context (Franklin, 1988), it is important to further examine how the leader may impact self-presentational concerns. The present study examined the impact of the exercise leader's gender and physique salience (i.e., the extent to which the body was emphasized) on SPE, state social anxiety (SSA), and state social physique anxiety (SPA-S) of women in a live exercise class. Eighty-seven college-aged female non- or infrequent exercisers (i.e., exercised 2 or fewer times per week) participated in a group exercise class led by one of four leaders: a female whose physique was salient; a female whose physique was non-salient; a male whose physique was salient; or a male whose physique was non-salient. Participants completed measures of SPE, SSA, and SPA-S prior to and following completion of a 30- minute group exercise class. In addition, a measure of social comparison to the exercise leader and other participants with respect to attractiveness, skill, and fitness was completed by participants following the exercise class. A MANOV A was conducted to examine differences between groups on postexercise variables. Results indicated that there were no significant differences between groups on measures ofSPE, SSA, or SPA-S (allp's > .05). However, when all participants were collapsed into one group, a MANOV A showed a significant time effect (F(3, 81) = 19.45,p < .05, 1')2= .419). Follow-up ANOVAs indicated that post-exercise SPE increased significantly, while SSA and SPA-S decreased significantly (SPE: F(I, 83) = 30.87,p < .001,1')2 = .27; SSA: F(I,83) = 11.09,p < .001, 1')2 = .12; SPA-S: F (1,83) = 42.79,p < .001, 1')2 = .34). Further, results of a MANOVA revealed that participants who believed they were less fit than other group members (i.e., made negative social comparisons) reported significantly more post-exercise SSA and SP A-S than those who believed they were more fit than the other participants (i.e., made positive comparisons; SSA: F(2, 84) = 3.46, p < .05, 1')2 = .08; SPA-S: F(2, 84) = 5.69, p < .05, 1')2 = .12). These results may indicate that successfully completing an exercise class may serve as a source of SPE and lead to reduced social anxiety and SPA-S in this population. Alternatively, characteristics of the exercise leader may be less important than characteristics of the other participants. These results also suggest that the types of social comparisons made may influence self-presentational concerns in this sample. Future research should examine how the type of social comparison (i.e., negative or positive) made to the other group members may either generate or reduce anxiety. Also, factors that contribute to the types of social comparisons made with other exercisers should be examined. Implications for practice and research are discussed.

Simulation of the postoperative trunk appearance in scoliosis surgery

Persistence of external trunk asymmetry after scoliosis surgical treatment is frequent and difficult to predict by clinicians. This is a significant problem considering that correction of the apparent deformity is a major factor of satisfaction for the patients. A simulation of the correction on the external appearance would allow the clinician to illustrate to the patient the potential result of the surgery and would help in deciding on a surgical strategy that could most improve his/her appearance. We describe a method to predict the scoliotic trunk shape after a spine surgical intervention. The capability of our method was evaluated using real data of scoliotic patients. Results of the qualitative evaluation were very promising and a quantitative evaluation based on the comparison of the simulated and the actual postoperative trunk surface showed an adequate accuracy for clinical assessment. The required short simulation time also makes our approach an eligible candidate for a clinical environment demanding interactive simulations.

Performance improvement of multiple Connections in AODV with the concern of Node bandwidth

Mobile Ad-hoc Networks (MANETS) consists of a collection of mobile nodes without having a central coordination. In MANET, node mobility and dynamic topology play an important role in the performance. MANET provide a solution for network connection at anywhere and at any time. The major features of MANET are quick set up, self organization and self maintenance. Routing is a major challenge in MANET due to it’s dynamic topology and high mobility. Several routing algorithms have been developed for routing. This paper studies the AODV protocol and how AODV is performed under multiple connections in the network. Several issues have been identified. The bandwidth is recognized as the prominent factor reducing the performance of the network. This paper gives an improvement of normal AODV for simultaneous multiple connections under the consideration of bandwidth of node.

Aproximación a un marco conceptual y teórico sobre la interculturalidad de los negocios internacionales

En este mundo globalizado los encuentros interculturales son, hoy más que nunca, una realidad para todas aquellas personas que por negocios, migración, viajes de turismo, intercambios estudiantiles, entre otros, han tenido un acercamiento con alguien de una cultura diferente. Así, el mundo empresarial no se ha quedado por fuera de ésta dinámica y debido a sus necesidades comerciales ha tenido que interactuar con otras culturas como parte de su estrategia de internacionalización.

Relación del burnout y el rendimiento académico con la satisfacción frente a los estudios en estudiantes universitarios

Los estudiantes se enfrentan cada vez más a retos y exigencias del medio que demandan una gran cantidad de recursos físicos y psicológicos de diversa índole. Muchos de ellos dejan sus estudios o disminuyen de manera considerable su rendimiento académico sin encontrar una explicación. Dos variables que han sido poco estudiadas en nuestro contexto y que pueden dar claridad a buena parte de esta situación son el burnout y la satisfacción. En esta investigación se estableció la relación del burnout, el rendimiento académico, con la satisfacción frente a los estudios en una muestra de 202 universitarios de la jornada nocturna de una universidad privada de Barranquilla, quienes respondieron el MBI-SS (Schaufeli, Martínez, Marques Pinto, Salanova, & Bakker, 2002). Los resultados indican correlaciones negativas entre agotamiento, cinismo, autoeficacia y rendimiento académico con la satisfacción frente al estudio, mientras que el vigor, dedicación y absorción se correlacionaron positivamente con esta. Por otro lado, el buen funcionamiento académico se correlaciona positivamente con las dimensiones del engagement y negativamente con el cinismo; de manera particular, ninguna de las variables se correlaciona con el agotamiento, a pesar de evidenciar cinismo y baja autoeficacia.

Description and analysis of pulmonary rehabilitation care programs current state in four cities of Colombia

Purpose: there are many studies reporting the benefits of pulmonary rehabilitation, but few of them exhibit the behavior and activities of these services. This article presents the characteristics of services, parts management and training level of team members, in addition to the variables or instruments used to measure the effectiveness and impact in these programs. Method: it was made a cross sectional convenience sample which included seven pulmonary rehabilitation services in four Colombian cities (Bogotá, Medellín, Manizales and Cali), selected by the coverage, for having at least one year of experience and for being formally established and recognized nationwide. The interdisciplinary team of each service answered a survey that was validated through a pilot test and expert consensus. Participation was voluntary. Results: labor onset pulmonary rehabilitation services correspond to an average of a decade, with COPD and asthma pathologies of attention. The programs are characterized by an outpatient treatment with an average duration of eight to twelve weeks, with a frequency of an hour three times a week. Also, the director of the service is regularly a pulmonologist and the coordinator a physiotherapist (57.14%). The posgradual training of these professionals is notable, and they report to have procedural, administrative and communicative skills, but qualify regular there research skills. The physical and technological resources are well tested. 71.42% have done impact studies, but only 28.57% have been published. All have in common training in upper limbs, lower limbs, respiratory muscles, counseling, functional assessment and quality of life. The effectiveness and impact of programs is measured by the walking test, quality of life questionnaires and activities of daily living.

Análisis de la influencia que ejercen las dinámicas de la violencia infantil en la favela Rocinha de Río de Janeiro, sobre la agenda del fondo de naciones unidas para la infancia (unicef): período 2008-2012

Este trabajo explica la realidad brasileña de las favelas, en particular las que se ubican en la ciudad de Rio de Janeiro. Así mismo, se pretende ubicar al lector en la favela Rocinha, y en uno de los principales problemas que enfrentan sus habitantes: la violencia infantil, o violencia contra los niños. La incapacidad del Estado para dar solución a este problema ha llevado a instituciones como UNICEF a crear alternativas para mitigarlo, por lo que es importante analizar esa nueva agenda, traducida en el primer ciclo del programa "Plataforma de Centros Urbanos". Se ha escogido el trabajo de campo como herramienta metodológica para dar cuenta de tal realidad, y para llegar a la conclusión de que un problema social puede, efectivamente, modificar la determinación de una agenda institucional.

La modulación de los efectos en el tiempo de las sentencias de nulidad de los actos administrativos en Colombia

El presente trabajo realiza un análisis sobre los diferentes fundamentos que ante la falta de regulación legal, nuestra jurisprudencia ha invocado para atribuirle efectos retroactivos –ex tunc- o efectos a futuro –ex nunc- a las sentencias de nulidad de los actos administrativos, los cuales van desde la asimilación de éste con el acto jurídico civil, hasta la pretendida identidad del acto administrativo general con la ley, todo enmarcado dentro de lo que se ha entendido por situaciones jurídicas consolidadas. Este estudio demuestra que la retroactividad o no retroactividad, no es una condición necesaria o automática de las sentencias de nulidad de los actos administrativos, porque tal idea anula reflexiones importantes que tienen que ver con la ponderación de principios básicos como la garantía de eficacia de los derechos fundamentales, la seguridad jurídica, la justicia material, la confianza legítima y la igualdad. Se impone así entender que los efectos temporales de las sentencias no se derivan de alguna formalidad del proceso, ni de la naturaleza del acto administrativo, ni del tipo de sentencia; estos son más bien una de las herramientas para que el juez a través de la modulación en cada caso, pueda darle eficacia a su sentencia y cumplir con las obligaciones que le impone la Constitución y la ley, que no son otras que garantizar la protección de derechos fundamentales y preservar el orden jurídico.
