Making Sense: Envy In Libanius' Declamation 30, Andrew Scholtz

Middle Eastern and Ancient Mediterranean Studies (MEAMS) Faculty Scholarship

Declamation, a genre famous for its sometimes extravagant fictions, has lately been approached as a vehicle for declaimers to reflect on realities familiar to them and their audiences. Reading Libanius' rarely discussed Declamation 30 in just such a self-reflective key, I argue that it explores the mindset of the phthoneros, the "envious man," as a way to make sense of risks posed by unscrupulous rivals. To shed light on this sense-making, I analyze High- and Late-Imperial emotion scripts foregrounding envy’s power to catalyze the formation of dysfunctional networks within and around competitive situations.

The Relationship Between Celebrity Worship And Psychotherapy Preferences, Sean Frydman M.S.

Selected Full Text Dissertations, 2011-

Celebrity worship (CW) is defined as an increased admiration toward a celebrity figure which may lead to excessive interest in their lives (McCutcheon et al., 2021). Intense CW has been found to be associated with a variety of pathological traits, suggesting that individuals with higher CW might benefit from psychotherapy (Sansone & Sansone, 2014). However, no research is available regarding psychotherapy preferences for this population. Research to date has found positive correlations between accommodating patients’ treatment preferences and greater treatment satisfaction and outcomes, stronger alliance, and reduced attrition (Iacoviello et al., 2007; Lindhiem et al., 2014; Swift et al., 2011, …

Psychotherapy Technique And Emotional Communication: The Relationship Between Technique Use In Psychotherapy And Patient Speech Styles Associated With The Referential Process, Sorrel Johnson M.S.

Selected Full Text Dissertations, 2011-

Linguistic analysis is a growing field within psychotherapy process research. Computerized measures have been developed to quantify qualities of speech associated with the Referential Process (RP), a construct describing the way in which people communicate emotional experience by cycling through different language styles (Bucci, 2021c). The three phases of RP are arousal, referential activity (RA), and reflection/reorganizing (R/R). Examining the latter two, the current study aimed to determine if therapists’ use of techniques was associated with immediate levels of patient RA and R/R in a sample of three archival psychotherapy sessions. Sessions were coded moment-by-moment (N=263 therapist speech turns) for …

Size Discrimination In Goldfish (Carassius Auratus), Johnna Patrick

Theses & ETDs

Quantitative abilities in fish have been previously observed, including in natural behaviors such as shoaling and various laboratory tasks. Two-choice visual discrimination tasks require individuals to differentiate between stimuli, and when conditioned, individuals can demonstrate learning of stimulus value. The concept of understanding ordinal relationships has been reported in goldfish (Carassius auratus) before, although no studies have explicitly tested primarily size discrimination. The current study tested four goldfish on their ability to perceive and swim through large vs. small holes, using an adapted methodology and expansion of similar literature. It also tested what the goldfish were learning during the discrimination …

The Efficacy Of Cgrp Antagonists Versus Other Non-Migraine Specific Medications As Prophylactic Treatment For Episodic And Chronic Migraine, Lauryn C. Hutto

The PA Department Journal of Medical Science

Introduction: Migraines are a disabling neurological condition affecting 12-15% of the population. Migraines are characterized by a unilateral throbbing headache lasting between 4 and 72 hours, often accompanied by photophobia, phonophobia, nausea, or vomiting. Until the approval of the first CGRP antagonist, Erenumab, in May 2018, the prophylactic treatment for migraines relied on non-migraine-specific medications, such as antihypertensives and antiepileptics. Studies have been done to determine the efficacy and safety of the new medications, but few have directly compared them to older non-migraine-specific medications used for prevention. The purpose of this paper is to compare the efficacy of CGRP …
