  • An Analysis of Hegemonic Social Structures in "Friends"
    "I'LL BE THERE FOR YOU" IF YOU ARE JUST LIKE ME: AN ANALYSIS OF HEGEMONIC SOCIAL STRUCTURES IN "FRIENDS" Lisa Marie Marshall A Dissertation Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY August 2007 Committee: Katherine A. Bradshaw, Advisor Audrey E. Ellenwood Graduate Faculty Representative James C. Foust Lynda Dee Dixon © 2007 Lisa Marshall All Rights Reserved iii ABSTRACT Katherine A. Bradshaw, Advisor The purpose of this dissertation is to analyze the dominant ideologies and hegemonic social constructs the television series Friends communicates in regard to friendship practices, gender roles, racial representations, and social class in order to suggest relationships between the series and social patterns in the broader culture. This dissertation describes the importance of studying television content and its relationship to media culture and social influence. The analysis included a quantitative content analysis of friendship maintenance, and a qualitative textual analysis of alternative families, gender, race, and class representations. The analysis found the characters displayed actions of selectivity, only accepting a small group of friends in their social circle based on friendship, gender, race, and social class distinctions as the six characters formed a culture that no one else was allowed to enter. iv ACKNOWLEDGMENTS This project stems from countless years of watching and appreciating television. When I was in college, a good friend told me about a series that featured six young people who discussed their lives over countless cups of coffee. Even though the series was in its seventh year at the time, I did not start to watch the show until that season.

  • Fungal Genomes Tell a Story of Ecological Adaptations
    Folia Biologica et Oecologica 10: 9–17 (2014) Acta Universitatis Lodziensis Fungal genomes tell a story of ecological adaptations ANNA MUSZEWSKA Institute of Biochemistry and Biophysics, Polish Academy of Sciences, Pawinskiego 5A, 02-106 Warsaw, Poland E-mail: [email protected] ABSTRACT One genome enables a fungus to have various lifestyles and strategies depending on environmental conditions and in the presence of specific counterparts. The nature of their interactions with other living and abiotic elements is a consequence of their osmotrophism. The ability to degrade complex compounds and especially plant biomass makes them a key component of the global carbon circulation cycle. Since the first fungal genomic sequence was published in 1996 mycology has benefited from the technolgical progress. The available data create an unprecedented opportunity to perform massive comparative studies with complex study design variants targeted at all cellular processes. KEY WORDS: fungal genomics, osmotroph, pathogenic fungi, mycorrhiza, symbiotic fungi, HGT Fungal ecology is a consequence of osmotrophy Fungi play a pivotal role both in encountered as leaf endosymbionts industry and human health (Fisher et al.

  • Chapter 1. Introduction
    Chapter 1: Introduction Chapter 1. Introduction Research and ecological context Importance of the mutualistic symbiosis Truffle-like fungi are an important component in many terrestrial ecosystems. They provide a food resource for mycophagous (‘fungus-eating’) animals and are an essential symbiont for many plant species (Claridge 2002; Brundrett 2009). Most truffle-like fungi are considered ectomycorrhizal (EcM) in which the fungus hyphae penetrate the plant root structure and form a sheath (‘Hartig Net’) around plant root tips. This enables the exchange of water, minerals, and metabolites between fungus and plant (Nehls et al. 2010). The fungus can form extensive networks of mycelium in the soil extending the effective surface of the plant-host root system. EcM fungi can also confer resistance to parasites, predators, pathogens, and heavy-metal pollution, as well as the breakdown of inorganic substrates (Claridge 2002; Gadd 2007; Bonfante & Genre 2010). EcM fungi can reproduce through mycelia (vegetative) growth or through spores. Truffle-like EcM fungi form reproductive below-ground (hypogeous) fruit-bodies (sporocarps) in which spores are entirely or partly enclosed within fungal tissue of the sporocarp (‘sequestrate’), and often referred to as ‘truffles’. The sporocarps of these fungi (‘truffles’) generally require excavation and consumption by mycophagous mammals for spores to be liberated and dispersed to new locations (Johnson 1996; Bougher & Lebel 2001). In contrast, epigeous or ‘mushroom-like’ fungi produce stipitate above-ground sporocarps in which spores are not enclosed within fungal tissue and are actively or passively discharged into the surrounding environment. Consequently, truffle-like taxa are considered to have evolved to be reliant on mycophagous animals for their dispersal.

  • 8 TV Power Games: Friends and Law & Order
    8 TV Power Games: Friends and Law & Order There is no such thing as a one-man show | at least not in television: one feature that all TV shows have in common is the combination of a large number of diverse contributors: producers, scriptwriters, actors, and so on. This is illustrated in Exhibit 8.1, which depicts the links between key contributors to the making and selling of a TV show. Solid lines repre- sent some form of contractual relationship, whereas dashed lines represent non-contractual relationships of relevance for value creation and value distribution. As is the case with movies, pharmaceutical drugs, and other products, the distribution of TV show values is very skewed: many TV shows are worth relatively little, whereas a few shows generate a very high value: For example, at its peak Emmy Award-winning drama ER fetched $13 million per episode.1 How does the value created by successful shows get divided among its various contrib- utors, in particular actors, producers and networks? Who gets the biggest slice of the big pie? In this chapter, I address this question by looking at two opposite extreme cases in terms of relative negotiation power: Law & Order and Friends. Law & Order | and profits The legal drama series Law & Order was first broadcast on NBC on September 13, 1990. (The pilot episode, produced in 1988, was intended for CBS, but the network rejected it, just as Fox did later, in both cases because the show did not feature any \breakout" characters.) By the time the last show aired on May 24, 2010, it was the longest-running crime drama on American prime time TV.
