Losing Our Minds To Madness: Paradigm Changes In Western European Perceptions Of Mental Illness, James Michael Cecil

History

Academia and scholarship of the 20th-century bred a renewed interest in mental illness throughout history. Despite an increase in the literature within the discourse surrounding "madness," scholars have generally failed to understand how and why Western European societies have viewed mental illness in various ways throughout recorded history. This paper argues that there remains an inherent, human desire to reject anything different from humanity, particularly mental illness, which is nearly impossible to fully comprehend. This is especially true in the case of how societies have institutionalized, punished, and subjugated the "mad" individual.

Revisiting Missions: Decolonizing Public Memories In California, Brenda M. Helmbrecht

English

Living in California seems to require interaction with the state’s twenty-one historic Spanish missions, either by visiting them as a tourist, driving by a mission in one’s neighborhood, or learning about them as a schoolchild. While the missions ostensibly celebrate California’s history, many promote an anachronistic and dishonest re-telling of history that elides the devastating impact of the missions on Native communities (both historically and today). The missions operate as largely uncontested tourist attractions that promote self-serving collective memories about California’s founding narrative. Rhetorical analysis, I argue, can lead to a more honest engagement with the “hard truths” of their …

Alleyway Revitalization: Planning For The Park Street - Pine Street Alley Between 12th Street And 13th Street, Paso Robles California, Mitchell Spector

City and Regional Planning

Alleyways generally refer to two kinds of paths. The first is a narrow pedestrian path between the walls of buildings in an urban environment. This type of alley is generally short and straight, although it may change in elevation. The second type of alley is a very narrow urban street or single lane. This is often used by slow moving vehicles and is more pedestrian friendly than a regular street. These alleys can be used as service roads for a variety of land uses and serves as a secondary vehicular network. It is very common in America to view alleyways …

Electrocardiographic Findings During Standard Hands Only Cpr And Hands Only Cpr Plus Pedal Cpr In Senior Rescuers, Laura Melany Yassa

Master's Theses

The standard first aid for a heart attack resulting in cardiopulmonary arrest is effective cardiopulmonary resuscitation (CPR). Chest compressions are most commonly performed on a flat surface with the rescuer kneeling next to the victim with one hand on top of the other on the sternum and elbows straight. This technique of being on the ground may be challenging for those without the mobility and strength to get up and down from the ground. In 2005, the American Heart Association (AHA) Guidelines listed “pedal”, or heel, compression as an acceptable alternative to standard chest compressions (Trenkamp & Perez, 2015). That …

James Petiver’S ‘Kind Friends’ And ‘Curious Persons’ In The Atlantic World: Commerce, Colonialism And Collecting, Kate S. Murphy

History

In 1695, James Petiver concluded the first ‘century’ of his Musei Petiveriani by observing that he had received the specimens described within it from his ‘Kind Friends from divers parts of the World’ and ‘Curious Persons…Abroad’. This essay examines Petiver’s network of such ‘Kind Friends’ and ‘Curious Persons’ in the Atlantic World. The composition of Petiver’s network reflected many of the broader patterns of English commerce in the Atlantic at the turn of the eighteenth century. Moreover, England’s growing overseas empire and its expanding commercial activity required a parallel expansion in maritime labour. Mariners were correspondingly central to Petiver’s work …
