Acceso de la mujer a puestos de dirección en organizaciones deportivas

Dos de los factores por los que se mide el progreso dentro de las sociedades avanzadas son la posición y estatus de las mujeres dentro de dicha sociedad. En el caso de España, la situación de la mujer ha cambiado mucho en de los últimos 40 años, y más concretamente a partir de su ingreso dentro del mercado laboral. De esta forma, sabemos que el avance hacia la igualdad en cualquier campo se ha estado produciendo, pero existen ámbitos en los que dicho avance tiene lugar de forma más lenta. Este es el caso de los puestos directivos donde la infrarrepresentación de la mujer en la toma de decisiones está observada en numerosos estudios anteriores. Pues bien, uno de los objetivos generales de la presente tesis doctoral es conocer las barreras actitudinales, lo que es conocido internacionalmente como el concepto “Techo de cristal”, en la consecución de este tipo de puestos por parte de las mujeres, dentro del sistema deportivo y en la Comunidad de Madrid. La metodología usada en esta investigación ha sido descriptiva, de corte transversal y estandarizada por medio de cuestionario, aplicado a una muestra final de 401 personas. Siendo la población objeto las personas que trabajan ocupando un puesto directivo dentro de entidades deportivas públicas y privadas ubicadas en la Comunidad de Madrid. Con una afijación proporcional según género y tipo de entidad. Los resultados obtenidos demuestran que a día de hoy todavía hay diferencias dentro de los puestos de responsabilidad, como por ejemplo, en el porcentaje de ocupación del puesto máximo, los salarios, etc, apareciendo diferentes actitudes que dificultan el acceso o promoción dentro de este tipo de puestos. Una de las principales conclusiones es que todavía no existe la equidad absoluta dentro de los puestos directivos de las organizaciones deportivas ubicadas en la Comunidad de Madrid, pero que el avance paulatino y constante se está produciendo para conseguir la plena igualdad. SUMMARY. Two of the factors that measured progress in advanced societies are the position and status of women within that society. In the case of Spain, the situation of women has changed a lot in the past 40 years, and more specifically from their entry into the labour market. In this way, we know that the progress towards equality in any field has been producing, but there are areas in which such progress takes place more slowly. This is the case of managerial posts where the under-representation of women in decision-making is observed in many previous studies. As well, one of the general objectives of this thesis it is know the attitudinal barriers, what is known internationally as the 'Glass ceiling' concept, in the pursuit of this type of posts by women within the sports system and in the community of Madrid. The methodology used in this research was descriptive, transversal and standardized cutting through questionnaire, applied to a final sample of 401 people. The target population to be people who work occupying a post steering within public and private sports organizations located in the community of Madrid. With a proportional affixation according to gender and type of entity. The results obtained show that today there are still differences in positions of responsibility, as for example, in the percentage of occupation since maximum, wages, etc., appearing different attitudes that hinder access to or promotion within this type of posts. One of the main conclusions is that there is still no absolute equity within the management positions of sport organisations located in the community of Madrid, but is occurring the gradual and steady progress to achieve full equality.

Calibration of calculation models of wooden guardrails with Operational Modal Analysis

This study analyses the differences between two calculation models for guardrails on building sites that use wooden boards and tubular steel posts. Wood was considered an isotropic material in one model and an orthotropic material in a second model. The elastic constants of the wood were obtained with ultrasound. Frequencies and vibration modes were obtained for both models through linear analysis using the finite element method. The two models were experimentally calibrated through operational modal analysis. The results obtained show that for the three types of wood under analysis, the model which considered them as an orthotropic material fitted the experimental results better than the model which considered them as an isotropic material.

FATS: a framework for annotation of travel blogs based on subjectivity

This paper describes a framework for annotation on travel blogs based on subjectivity (FATS). The framework has the capability to auto-annotate -sentence by sentence- sections from blogs (posts) about travelling in the Spanish language. FATS is used in this experiment to annotate com- ponents from travel blogs in order to create a corpus of 300 annotated posts. Each subjective element in a sentence is annotated as positive or negative as appropriate. Currently correct annotations add up to about 95 per cent in our subset of the travel domain. By means of an iterative process of annotation we can create a subjectively annotated domain specific corpus.

Is the polarity of content producers strongly influenced by the results of the event?

This paper presents an approach to compare two types of data, subjective data (Polarity of Pan American Games 2011 event by country) and objective data (the number of medals won by each participating country), based on the Pearson corre- lation. When dealing with events described by people, knowledge acquisition is difficult because their structure is heterogeneous and subjective. A first step towards knowing the polarity of the information provided by people consists in automatically classifying the posts into clusters according to their polarity. The authors carried out a set of experiments using a corpus that consists of 5600 posts extracted from 168 Internet resources related to a specific event: the 2011 Pan American games. The approach is based on four components: a crawler, a filter, a synthesizer and a polarity analyzer. The PanAmerican approach automatically classifies the polarity of the event into clusters with the following results: 588 positive, 336 neutral, and 76 negative. Our work found out that the polarity of the content produced was strongly influenced by the results of the event with a correlation of .74. Thus, it is possible to conclude that the polarity of content is strongly affected by the results of the event. Finally, the accuracy of the PanAmerican approach is: .87, .90, and .80 according to the precision of the three classes of polarity evaluated.

Fashion in Actions on Social Media – Spanish SME Fashion Brands Case Studies

Fashion is one of the most vibrant sectors in Europe and important contributors to the European Union (EU) economy. In particular, Small and Medium Enterprises (SMEs) play a major part in European fashion industry (EU 2012). Just like fashion, where people¿s style has inherently meant to be shared as it is foremost a representation of one¿s self-image, social media allow the reflection of ones' personality and emotions. Although fashion practitioners have embraced social media in their marketing activities, it is still relatively few known at an academic level about the specificities of fashion industry when approaching social media marketing (SMM) strategies. This study sets out to explore fashion companies' SMM strategy and its activities. From an exploratory approach, we present case studies of two Spanish SME fashion companies, anonymously named hereafter as Company A and Company B, to deepen our understanding on how fashion brands implement their SMM strategy. Company A offers high-end fashion products while Company B produces medium fashion products. We analyzed the case studies using qualitative (interviews to companies' executives) and a mix of qualitative and quantitative (content analysis of companies' social media platform) methods. Public posts data of both companies' Facebook brand pages were used to perform the content analysis. Our findings through case studies of the two companies reveal that branding-oriented strategic objectives are the main drivers of their SMM implementations. There are significant differences between both companies. The main strategic action employed by Company A is engaging customers to participate into brand's offline social gathering events by inviting them through social media platform, while Company B focuses its effort on posting product promotion related contents and engaging influencers such as fashion bloggers. Our results are expected to serve as a basis of further investigations on how SMM strategy and strategic actions implemented by fashion brands may influence marketing outcomes.
