The neo-liberal state and the crisis of public service broadcasting in the Anglo-American democracies /

The NeO'liberal State and the Crisis ofPublic Service Broadcasting in the Anglo-American Democracies The purpose ofthis analysis ofthe present condition ofpublic service broadcasting in the Anglo- American democracies was to investigate whether such media can still be regarded as the primarypublic spherefor a dialogue between each nation 's civil society and the State. The motivationfor this thesis was based on a presumption that such fora for public discussion on the central issues of each society have become viewed as less relevant bypoliticians andpolicy-makers and thepublics they were intended to serve in the Anglo-American democracies over thepast two decades. It is speculated that this is the case because ofa beliefthat the post-war consensus between the respective States andpublics that led to the construction of the Keynesian Welfare State and the notion ofpublic service broadcasting has been displaced by an individualistic, neo-liberal, laissez-faire ideology. In other words, broadcasting as a consumer-oriented, commercial commodity has superseded concerns pertaining to the importance ofthe public interest. The methodology employed in this thesis is a comparative analysisfrom a criticalpolitical economy perspective. It was considered appropriate to focus on the United Kingdom, Australia, Canada and the\ United States because they comprise the four largest Anglo-American nations with democratic political systems andprimarily market economies. Justificationfor this particular sample is reinforced by thefact that case study countries also share a common socio-political and economic tradition. The evidence assembledfor this thesis consisted almost exclusively ofexisting literature on the subjects ofpublic service broadcasting, global economic andpolitical integration, and the ascendance ofthe 'free-market ' ethos in Western democracies since the late mid- to late-1970s. In essence, this thesis could be considered as a reinterpretation ofthe existing literature relevant to these issues. Several important common features werefound among the political, economic and broadcasting systems of the four case study nations. It is proposed that the prevalence of the neo-liberal world view throughout the political and policy environments of the four countries has undermined the stability and credibility of each nation 's national public service broadcasting organization, although with varying intensity and effect,. Deregulation ofeach nation 's broadcasting system and the supremacy ofthe notion of 'consumer sovereignty' have marginalized the view of broadcasting on any basis other than strictly economic criteria in thefour case study countries. This thesis concludes that,for a reconstruction ofa trulyparticipatory anddemocraticpublicsphere to be realized in the present as well as thefuture, a reassessment ofthe conventional concept ofthe 'public sphere ' is necessary. Therefore, it is recommended that thefocus ofpolicy-makers in each Anglo-American democracy be redirectedfrom that which conceived ofan all-encompassing, large, state-ownedand operated public broadcasting service toward a view which considers alternativeforms ofpublic communication, such as local community and ethnic broadcasting operations, that are likely to be more responsive to the needs of the increasingly diverse and heterogeneous populations that comprise the modem Anglo-American democracies. The traditional conception of public broadcasters must change in accordance with its contemporary environment if the fundamental principles of the public sphere and public service broadcasting are to be realized.

Effect of pH on non-photochemical quenching in spinach photsystem 2 particles as measured by picosecond fluorescence decay kinetics

Single photon timing was used to study picosecond chlorophyll a fluorescence decay kinetics of pH induced non-photochemical quenching in spinach photosystem 2 particles. The characteristics of this quenching are a decrease in chlorophyll a fluorescence yield as well as a decrease in photochemistry at low pH. Picosecond kinetics of room temperature fluorescence temporally resolve the individual components of the steady state fluorescence yield into components that are related to primary energy conversion processes in photosystem 2. Four components were resolved for dark adapted (Fo), light saturated (Fm), and chemically reduced (Nadithionite) photosystem 2 reaction centres. The fastest and slowest components, indicative of energy transfer to and energy capture by the photosystem 2 reaction centre and uncoupled ("dead") chlorophyll, respectively, were not affected by changing pH from 6.5 to 4.0. The two intermediate components, indicative of electron transfer processes within the reaction centre of photosystem 2, were affected by the pH change. Results indicate that the decrease in the steady state fluorescence yield at low pH was primarily due to the decrease in lifetime and amplitude of the slower of the intermediate components. These results imply that the decrease in steady state fluorescence yield at low pH is not due to changes in energy transfer to and energy capture by the photosystem 2 reaction centre, but is related to changes in charge stabilization and charge recombination in the photosystem 2 reaction centre.

Investigating the effects of arousal state on cognitive performance in individuals with and without mild head injury

We examined the cognitive and emotional sequelae following mild head injury (MHI; e.g., concussion) in high-functioning individuals and whether persons with MHI pre~ent, both physiologically and via self-report, in a manner different from (i.e., underaroused) that of persons who have no history of head injury. We also investigated the effect arousal state ~as on the cognitive performance of this population. Using a quasiexperimental research design (N = 91), we examined changes in attention, working memory, and cognitive flexibility (subtests ofthe WAIS-III, 1997,WMS-III, 1997, & DKEFS, 2002) as a function of manipulated arousal (i.e., induced psychosocial stress/activation; reduced activation/relaxation). In addition to self-reported arousal and state anxiety (State-Trait Anxiety Inventory; Speilberger, 1983a) measures, physiological indices of arousal state (i.e., electrodermal responsivity, heart rate, and respiration activity) were recorded (via Polygraph Professional Suite, 2008) across a 2.5 hour interval while completing various cognitive tasks. Students also completed the Post-concussive Symptom Checklist (Gouvier et aI., 1992). The results demonstrate that university students who report a history ofMHI (i.e., "altered state of consciousness") experience significantly lower levels of anxiety, were physiologically underaroused, and were less responsive to stressors in their environment, compared to their non-~HI cohorts. As expected, cognitive flexibility (but not other neuropsychological measures of cognition) was advantaged with increased stress, and disadvantaged with reduced stress, in persons with reported MHI, but not for those without reported MHI which provided limited support for our hypothesis. Further, university students who had no complaints related to their previous MHI endorsed a greater number of traditional post-concussive symptoms in terms of intensity, duration and frequency as compared to students who did not report a MHI. The underarousal in traumatic brain injury has been associated with (ventromedial prefrontal cortex) VMPFC disruption and may be implicated in MHI generally. Students who report sustaining a previous MHI may be less able to physiologically respond and/or cognitively appraise, stressful experiences as compared to their no-MHI cohort and experience persistent, long-lasting consequences despite the subtle nature of a history of head injury.

Decoding algorithms using side-effect machines

Bioinformatics applies computers to problems in molecular biology. Previous research has not addressed edit metric decoders. Decoders for quaternary edit metric codes are finding use in bioinformatics problems with applications to DNA. By using side effect machines we hope to be able to provide efficient decoding algorithms for this open problem. Two ideas for decoding algorithms are presented and examined. Both decoders use Side Effect Machines(SEMs) which are generalizations of finite state automata. Single Classifier Machines(SCMs) use a single side effect machine to classify all words within a code. Locking Side Effect Machines(LSEMs) use multiple side effect machines to create a tree structure of subclassification. The goal is to examine these techniques and provide new decoders for existing codes. Presented are ideas for best practices for the creation of these two types of new edit metric decoders.

The effect of acute exercise type on body image attitudes

The current study examined the effect of two types of acute exercise (resistance and mind-body yoga) on state body image attitudes, to see which, was most effective at reducing body image concerns. I t was hypothesized that both types of exercise would lead to improvements in body image, with yoga showing the biggest benefits. Collegeaged female non/infrequent exercisers (n = 40) completed state measures of body satisfaction, social physique anxiety (SPA), and appearance orientation prior to and following participation in a single yoga and resistance class. Participation in the yoga class was associated with decreases in SPA and increases in body satisfaction. However, participation in the resistance class was associated with no changes in any of the study variables. These findings indicate participation in a single yoga class may have positive effects on body image attitudes, which may encourage non-exercisers to become more active.

Hoosiers on the Hardwood: A Critical Examination of Indiana Basketball Culture and its Effect on Identity Formation

The purpose of this research was to examine the nexus at which Indiana basketball and the state’s ‘hoosier’ identity meet. More specifically, this thesis interrogates the romanticization of this sporting culture for its pedagogical role in the creation of twenty-first century ‘hoosier’ bodies. Adopting a theoretical orientation rooted in critical race theory, I argue that Indiana’s basketball culture represents a normalized / normalizing structure underneath which Otherness is reified to produce hypervisible “different” outsiders (‘non-hoosiers’), and invisible “disciplined” insiders (i.e. ‘hoosiers’). Utilizing data gleaned over a two-month period spent conducting fieldwork in the “hoosier state” (document analysis, unstructured interviewing, and participant observation), I specifically tailor my analysis to uncover people’s understanding, negotiation, and performance of this regional and national subject position. From this point of inquiry, authentic ‘hoosierness’ comes to be represented, known, practiced, and felt in relation to hierarchies of power that privilege white, hypermasculine, rural, and conservative bodies.
