La dificultad de medir

El análisis de redes se ha popularizado porque ha facilitado abordar relaciones estructurales que otros métodos ignoraban, sin embargo todavía quedan pendientes algunos problemas metodológicos que conviene abordar para buscar explicaciones más complejas, como por ejemplo la generación de índices de centralidad donde se manejen conexiones con peso y atributos diferenciados. En este artículo se apuntan algunas de las problemáticas encontradas en nuestro análisis de la red de poder mexicana para mostrar la centralidad de los actores y la dificultad de generar un índice de poder.Network analysis has popularized because it has facilitated approaching structural relationships which other methods ignored, however, still some methodological problems remain to be solved in the search of more complex explanations, such as the generation of centrality indexes in which connections with weight and attributes. In this article we indicate some of the problems we found in our centrality analysis of the Mexican network of power and the difficulty to generate an index of power

An Evaluation Of Selected Seventh-day Adventist Sermons In Mexico Against Certain Criteria For Biblical Preaching

Problem. Some of the Seventh-day Adventist sermons preached in Mexico appear to offer limited biblical content. It has been observed that overtaxed ministers often present material that does not correspond to some of the members\u27 expectations. Since the word of God is central in the praise and adoration of God and constitutes the message to be proclaimed, it is important for preachers to understand better ways to preach the Good News. Method The purpose of this project was to explore current Seventh- day Adventist preaching in Mexico with respect-to sermon content. The theology of God\u27s proclamation places great responsibility upon preachers of His Good News, and it is essential that all clearly perceive this God given duty. A request for recorded sermons was sent to ministers who had studied homiletics at Montemorelos University. The first twenty tape recorded sermons that arrived were analyzed using three criteria based on an examination of the origins of biblical preaching and of the contemporary literature on the subject. Data concerning the biblical content and delivery of the sermons, the preachers, and the sermon settings were considered in the analysis. Recommendations The project suggests the need for a well defined theology of preaching available to preachers as a basis for guiding them in biblical preaching, for ministers to study the Scriptures to better proclaim the gospel, and for in-service education for Mexican preachers

A qualitative case study examination of athlete ally using social movement theory.

The following study answered the call for more social movement related studies in sport (Davis-Delano & Crosset, 2008) and lessened the paucity of literature on athlete activism. The purpose of this study was to examine a sport specific social movement organization, Athlete Ally, using Social Movement Theory. Social Movement Theory is guided by three tenets: Resource Mobilization Theory (Edwards & McCarthy, 2004), Political Process Theory (Kriesi, 2004), and Cultural Theory/Frame Analysis (Williams, 2004). Each of these tenets was used to examine the resources exchanged between Athlete Ally and their athlete constituents, determine the strategies for engaging with various sport (i.e. NCAA and NBA) and non-sport governing bodies (i.e. U.S. Government), and understand the tactics for ensuring frame resonance by Athlete Ally. The following qualitative case study was conducted through seven employee or board member interviews with Athlete Ally and an examination of salient organizational documents. Findings indicate that a SMO can provide resources to minimize the impact of negative consequences for engaging in activism. For instance, providing a safe space and access to other athlete activists can allow an athlete to engage in activism knowing a SMO is supporting the athlete. On the other side, athletes also provide SMOs with resources, most notably a vast social-network of other constituents. From recruitment of other athlete ambassadors, like teammates, or raising awareness for the organization, athletes can be proficient resources that few other celebrities can match. Those resources can then be utilized to engage with various governing bodies. Typically, when Athlete Ally engages with a protagonist entity, they employ strategies of collaboration. Conversely, Athlete Ally utilizes combative strategies when faced with an antagonistic entity. Despite these strategies, Athlete Ally has to ensure their frames resonate with the intended audience to actually enact change. Athlete Ally accomplishes this by utilizing athletes’ stories, objective statistics, and a diverse staff to increase the salience of their messages. Further findings and results are discussed. Overall, the study’s findings speak to the mutually beneficial relationships sport specific SMOs and athletes can develop to further the goals of a social movement organization

Galaxy Evolution: The DRaGONS Survey and Luminosity Functions With Photometric Redshifts

This thesis examines two complementary approaches to the study of galaxy evolution using multiwavelength large area galaxy surveys. The first part of the thesis focuses on a statistical study of the overall galaxy population, namely the evolution of galaxy luminosity functions, while the second part of the thesis aims to study an interesting population of rare galaxies selected based on their radio and optical properties, namely high redshift radio galaxies selected from SDSS and FIRST. We compute the luminosity function (LF) for the general galaxy population and as a function of type using photometric redshifts derived from the SDSS Southern Survey. We present a new maximum likelihood estimator and show that it accounts for the uncertainties associated with photometric redshifts. In addition to three existing parameterizations, we introduce the use of cubic BSplines to fit the luminosity function. We show evidence for the evolution of the luminosity function, but defer much of the analysis until a better photometric redshift dataset is available. The second part of the thesis describes the Distant Radio Galaxies Optically Non- detected in SDSS (DRaGONS) survey. Our new selection criteria appear to be very efficient at identifying high redshift radio galaxies, including a substantial population of shallow spectrum radio sources missed by competing selection techniques. These sources, when confirmed, will have a dramatic effect on the empirical z-alpha relation. I describe the environment of early galaxy formation through the study of nearby Extremely Red Objects (EROs) and faint K-band galaxy counts. We find an excess number of faint EROs and galaxies around a subset of DRaGONS candidates, indicating that massive galaxies form in overdense environments. 10% of DRaGONS galaxies are redder than expected, which indicates moderate obscuration and the possible presence of ongoing star formation. These objects, which we dub Red DRaGONS, could represent a significant radio-loud population missing from optically selected AGN surveys
