Ralph J. Perk, the “New ethnicity”, and the making of urban ethnic republicans
Historians seeking to explain the late twentieth century rightward shift of urban ethnic whites have tended to ignore the shifting meaning and content of white ethnic identity in this transition, and the utility of these changes to conservative political discourse. This article, focusing on the ethnic strategies of the Republican mayor of Cleveland, Ralph Perk, seeks to illustrate the importance of the “New Ethnicity” of the 1970s, and its reconceptualization of white ethnicity as a series of “values”, in the making of urban ethnic Republicans. In doing so it reorients our understanding of Perk – the “Ethnic Mayor” – and places ethnicity at the heart of the conservative insurgency reshaping urban and national politics during this period
Cleveland Mayor Ralph J. Perk: Strong Leadership During Troubled Times
This book is a tribute to one of Cleveland’s greatest leaders. Ralph J. Perk embodied the quintessential 20th century politician. A dedicated administrator with both insight and foresight, he dedicated nearly fifty years to public service. During his six-year tenure as mayor, Cleveland went through extraordinary economic, political and social changes. The citizenry demanded strong leadership and Ralph Perk provided it. An optimistic leader with strong moral and religious convictions, he never walked away from a challenge.https://engagedscholarship.csuohio.edu/clevmembks/1017/thumbnail.jp
A short history of the European Association of Preventive Cardiology (EAPC)
De Backer G, Perk J, Wood D, et al. A short history of the European Association of Preventive Cardiology (EAPC). European Journal of Preventive Cardiology . 2022: zwac027.The history of the EAPC is closely related to the history of the European Society of Cardiology (ESC). The ESC decided at the turn of the century to overcome the splitting into 27 topic related Working Groups with great differences in size and activities and to create a new organizational concept based on Associations, each having an official ESC scientific journal and an annual ESC connected congress. The European Association for Cardiovascular Prevention and Rehabilitation was built on the fundaments of epidemiology and prevention, exercise physiology, cardiac rehabilitation and sports cardiology. The official journal of the Association was launched in 2003 and the first EuroPRevent Congress was held in Athens in 2006. During the following years, the different interests of the founding working groups came closer together, which resulted in a name change of the Association into "European Association of Preventive Cardiology" and of the journal into "European Journal of Preventive Cardiology". The name change marked the migration of Preventive Cardiology to centre stage in the ESC. This document summarizes how and from where the EAPC started and where it stands now.

PERK-mediated expression of peptidylglycine α-amidating monooxygenase supports angiogenesis in glioblastoma
PKR-like kinase (PERK) plays a significant role in inducing angiogenesis in various cancer types including glioblastoma. By proteomics analysis of the conditioned medium from a glioblastoma cell line treated with a PERK inhibitor, we showed that peptidylglycine α-amidating monooxygenase (PAM) expression is regulated by PERK under hypoxic conditions. Moreover, PERK activation via CCT020312 (a PERK selective activator) increased the cleavage and thus the generation of PAM cleaved cytosolic domain (PAM sfCD) that acts as a signaling molecule from the cytoplasm to the nuclei. PERK was also found to interact with PAM, suggesting a possible involvement in the generation of PAM sfCD. Knockdown of PERK or PAM reduced the formation of tubes by HUVECs in vitro. Furthermore, in vivo data highlighted the importance of PAM in the growth of glioblastoma with reduction of PAM expression in engrafted tumor significantly increasing the survival in mice. In summary, our data revealed PAM as a potential target for antiangiogenic therapy in glioblastoma
The Life & Times of Ralph J. Perk
Cleveland’s economic transformation from heavy manufacturing to health-related industries has not been easy. Many leaders are still discussing what course of action to follow. Studying successful policies from past politicians may afford new insight into how to handle this transition.
Effective politicians have always worked well with others; established achievable goals; and advanced community objectives. Mayor Ralph J. Perk was no exception. He initiated many broad-based programs while never forgetting the needs of the electorate.
A Web site dedicated to his life and work is intended to shed some new light on his political mastery during a very turbulent time in our city’s history. Many of his policies worked well then, perhaps they can be successfully replicated in today’s world.https://engagedscholarship.csuohio.edu/cmpex/1043/thumbnail.jp
