Research article of Global journal of Economics and Business Administration  CEO Turnover and IPO Performance Guanyu Chen1 and Hengfeng Xu2* 1Hangzhou Hump Supply Chain Limited 2Lancaster University Management School Previous research presents extensive conclusive results regarding the association between firm performance and CEO turnover. However, the issue of CEO turnover is still rarely investigated with regard to the usefulness Initial Public Offerings (IPOs) performance in the topic of Chief Executives Officers (CEOs) turnovers. The principle objective of this study is to investigate whether the likelihood of the CEOs turnover is inversely correlated with the IPO performance of the firm. This study is conducted by employing the U.S. sample data consists of 462 firms including 173 CEO turnover events within 5 years after the IPO offering during the period between 2003 and 2013, and it is mainly concluded that CEO turnover matters with respect to firm IPO performance, however, only for IPO long-term performance, rather than short-term performance.

DIFFERENTIAL DIAGNOSES OF ANGIOKERATOMAS

Review Article of American Journal of Dermatological Research and Reviews DIFFERENTIAL DIAGNOSES OF ANGIOKERATOMAS Jesús del Pozo1*, Felipe Sacristán2, Manuel Gómez Tellado3, Servicios de Dermatología1, Anatomía Patológicay2, Cirugía Pediátrica3 1Unidad de Anomalías Vasculares Pediátricas, Instituto de Investigación Biomédica de A Coruña (INIBIC). 2Complexo Hospitalario Universitario de A Coruña (CHUAC). 3Sergas. Universidade da Coruña (UDC). As Xubias, 84. 15006, A Coruña, España. Angiokeratomas (AK) are probably the vascular lesions that induce more confusion in the literature. The most accepted classification of AK was performed by Imperial and Helwig , and they divide these lesions into five classical types: Mibelli’s AK, Fordyce’s AK, corporis diffusum AK, circumscribed naeviforme AK and solitary or multiple acquired angiokeratomas. Nevertheless, in the clinical practice, is not unusual to see AK type lesions associated to different types of vascular anomalies, and these lesions have difficult handling. In ISSVA classification AKs have been included as vascular anomalies provisionally unclassified. We perform the differential diagnoses of AKs and according to clinical picture, histopathological aspect, immunohistochemical markers and radiological findings proposed to divide AKs mainly in two groups. Primary AKs are the classical types. The new immunohistochemical findings suggest that these lesions might be included as mixed capillary-lymphatic malformations. Secondary AKs are related with different vascular anomalies, secondary to other process with lymphatic obstruction, related to drugs, or associated with no vascular lesions as lymphoid lesions. Different underlying vascular anomelies might be related with AKs including deep capillary-lymphatic malformations (CLM), venous-lymphatic malformations (VLM), capillary-lymphatic-venous malformations (CLVM) (Klippel-Trenaunauy Sd), deep lymphatic malformations (LM), venous malformations (VM) as hyperkeratotic venous malformation, cavenomatous cerebral malformations, traumatic arteriovenous fistula and eccrine angiokeratomatous hamartoma. Clinical aspect, radiological studies and histopathological examination might help to do a correct diagnosis of this heterogenous entity. Keywords: Angiokeratomas; Vascular lesions ...

Contradiction and Double Binds in COVID-19 Face Covering Recommendations

Review article of International Research Journal of Health Education Contradiction and Double Binds in COVID-19 Face Covering Recommendations Tyler Spradley, Ph.D.1*, Elizabeth L. Spradley, Ph.D.1  1Stephen F. Austin State University. The global coronavirus pandemic incited swift public health recommendations and education in the United States and throughout the world to reduce the spread of the virus. In the U.S., the White House Coronavirus Task Force, the “Slow the Spread” campaign in 15 and 30-day increments, the Centers for Disease Control and Prevention (CDC), and other public health organizations and representatives weighed in on the role of face coverings to counter COVID-19 threats to public health. Face coverings became a contested public health recommendation. This article rhetorically analyzes contradiction in COVID-19 face covering recommendations and the ensuant double-binds. Analysis of press conferences, national public health websites, and the “Slow the Spread” campaign reveals contradictions in individual risk-averse public health recommendations, specifically face coverings. Contradictions were categorized into: uncover-cover, risky-risk averse, voluntary-recommended-required, and politically right-left. Implications of contradictory messages create double binds for the public seeking to adhere to public health recommendations for personal and public safety. Double binding public health messages undermine public health goals because double binds often result in maladaptive, inappropriate responses. Conclusions assert that to be a responsible citizen of personal and public health in a viral pandemic is a contested and contradictory accomplishment.

Obfuscated Signaling: Analyzing and Predicting Changes in Branding in the Fashion Industry

Research article of Global journal of Economics and Business Administration Obfuscated Signaling: Analyzing and Predicting Changes in Branding in the Fashion Industry Solomon Son Palisades Park Jr/Sr High School As time goes on, sentiments change. This statement is perhaps best observed in the mercurial nature of the fashion industry, where styles and brands are constantly evolving. These changes may seem random, or simply a product of what celebrities enjoy at the moment. However, upon closer investigation, an interesting trend appears: the movement of designer brands towards smaller and more simplistic logos. These changes are by no means insignificant; advertising is one of the most important aspects of a brand, and its costs are substantial. Because of these costs, brands only aim to change logos when they feel they need to match a change in fashion or a cultural shift. Thus, by analyzing when and how brands change their logos, researchers can predict and capitalize upon trends in the fashion industry. However, it is still unclear as to why brands have specifically moved to more simplistic appearances. What is the appeal for newer styles to be more discreet, humble, and less ostentatious? To understand this phenomenon, we propose a model that analyzes the change in preferences and motivations in both fashion and culture across generations. Using this model, we achieve results that give further insight into how this knowledge can be used to predict and capitalize upon future trends.

Pure alphafetoprotein producing neuroendocrine carcinoma of the stomach: A case report

Case Report of Open Journal of Gastroenterology and Hepatology Pure alphafetoprotein producing neuroendocrine carcinoma of the stomach: A case report Chen-Wei Chu1, Chien-ho Tsai2, Yu-Huan Huang3, Chun-I Tsai4, Swei-hsiung H Tsung5 1.Department of Medicine, Taipei Veterans General Hospital, Yuanshan branch, Yuanshan, Yilan, Taiwan. 2.Deparment of surgery, National Yang-Ming University Hospital, Yilan.Taiwan. 3.Department of Nursing, National Yang-Ming University Hospital, Yilan, Taiwan 4.Chun-I Tsai Medical Clinic. Yilan, Taiwan. 5.Department of Pathology, St Mary’s Hospital, Loudong, Yilan, Taiwan Alpha-fetoprotein-producing gastric carcinoma (AFP-GC) is a rare malignant tumor, and has been regarded as a distinct category because of its particularly aggressive biological behavior and poor patient prognosis. In the literature, AFP-GC was never reported in neuroendocrine carcinoma of the stomach. In this article, we described a 60-year old man who sought medical attention because of epigastric pain and poor appetite. His laboratory data were within normal limits except for elevated serum level of alpha-fetoprotein. He was found to have an ulcer on gastroscopic examination which led to the final diagnosis of AFP producing neuroendocrine carcinoma of the stomach. He underwent a radical gastrectomy followed by chemotherapy using leucovorin and 5-fluorouracil.His disease was brought under remission for only six months before radiological recurrence occurred. His recurrent disease was treated with irinotican plus cisplatin without a significant response. His prognosis looked grave. We reported the first case of AFP producing gastric neuroendocrine carcinoma to share our experience. Keywords: gastric cancer. Alpha-fetoprotein. Neuroendocrine carcinoma. Chemotherapy.

Dermatological adverse events of immune checkpoint inhibitors

Review Article of American Journal of Dermatological Research and Reviews Dermatological adverse events of immune checkpoint inhibitors Kevin Yang1, Khurram Yusuf2 1Dermatology, UAB School of Medicine, Birmingham, AL 35294 2Kendriya Vidyalaya, Jabalpur, MP 482004, India Treatment with immune checkpoint inhibitors is a landmark in the treatment of melanoma and other cancers. These treatments have been very effective and have increased the survival of cancer patients. The promise of immunotherapy also comes with a variety of adverse events. One of the common sites of immune related adverse events (irAEs) is skin. The cutaneous irAEs present a unique challenge to the success of immunotherapy. It is important to diagnose and understand the mechanism related to these cutaneous irAEs to increase the effectiveness of immune checkpoint inhibitor therapy. In this review, we have characterized the various cutaneous irAEs associated with immune checkpoint inhibitor therapies and their possible mechanisms.
