    The Gezi Park Protests and the Escalation and De-escalation of Political Contention
    (Taylor and Francis, 2019) Demirel-Pegg, Tijen; Political Science, School of Liberal Arts
    This study argues that escalation and de-escalation processes lie at the heart of protest campaigns. These processes are largely determined by the interactions between protesters and governments, as well as the timing and types of strategies and tactics employed. The study examines the dynamics between the Turkish government and the protesters during the 2013 Gezi Protest Campaign. This campaign escalated quickly by generating massive support from different segments of the Turkish society in its earlier days, and then de-escalated and eventually demobilized without securing major concessions. By using original data collected from a Turkish newspaper, Cumhuriyet, the study illustrates how the trajectory of the Gezi campaign changed in response to the interactive dynamics between the government and the dissidents.

    Long-Term Alcohol Drinking Reduces the Efficacy of Forced Abstinence and Conditioned Taste Aversion in Crossed High-Alcohol-Preferring Mice
    (Wiley, 2016-07) O’Tousa, David Scott; Grahame, Nicholas Joseph; Psychology, School of Science
    BACKGROUND: Negative outcomes of alcoholism are progressively more severe as the duration of problem of alcohol use increases. Additionally, alcoholics demonstrate tendencies to neglect negative consequences associated with drinking and/or to choose to drink in the immediate presence of warning factors against drinking. The recently derived crossed high-alcohol-preferring (cHAP) mice, which volitionally drink to heavier intoxication (as assessed by blood ethanol [EtOH] concentration) than other alcohol-preferring populations, as well as spontaneously escalating their intake, may be a candidate to explore mechanisms underlying long-term excessive drinking. Here, we hypothesized that an extended drinking history would reduce the ability of 2 manipulations (forced abstinence [FA] and conditioned taste aversion [CTA]) to attenuate drinking. METHODS: Experiment 1 examined differences between groups drinking for either 14 or 35 days, half of each subjected to 7 days of FA and half not, to characterize the potential changes in postabstinence drinking resulting from an extended drinking history. Experiment 2 used a CTA procedure to assess stimulus specificity of the ability of an aversive flavorant to decrease alcohol consumption. Experiment 3 used this taste aversion procedure to assess differences among groups drinking for 1, 14, or 35 days in their propensity to overcome this aversion when the flavorant was mixed with either EtOH or water. RESULTS: Experiment 1 demonstrated that although FA decreased alcohol consumption in mice with a 14-day drinking history, it failed to do so in mice drinking alcohol for 35 days. Experiment 2 showed that the addition of a flavorant only suppressed alcohol drinking if an aversion to the flavorant was previously established. Experiment 3 demonstrated that an extended drinking history expedited extinction of suppressed alcohol intake caused by a conditioned aversive flavor. CONCLUSIONS: These data show that a history of long-term drinking in cHAP mice attenuates the efficacy of interventions that normally reduce drinking. Analogous to alcoholics who may encounter difficulties in limiting their intake, cHAP mice with long drinking histories are relatively insensitive to both abstinence and signals of harmful consequences. We propose that the cHAP line may be a valid model for adaptations that occur following the extended heavy alcohol drinking.
