David Tracy on fragments, fragmentation, and frag-events: On picking up a conversation

This contribution offers a review of David Tracy’s recent collection of essays entitled Fragments: The Existential Situation of Our Time (2020). This volume is quite an event since Tracy’s last monograph was published in 1994. This review gives an account of the continuity and discontinuity in Tracy’s oeuvre with reference to themes such as conversation, fragments, the Infinite, and an analogical imagination. It also mentions some other jewels found in Fragments by picking up on a conversation with Tracy that started with the author’s doctoral thesis on Tracy, completed in 1992.

Risk and Resilience Management as a Response to COVID-19 Pandemic Outbreak. Towards a New and Refreshing Approach

Today’s global business environment is dynamic and is subject to continuous changes that could create opportunities and threats for any organization. The lack of an adequate preparation exposes enterprises to environmental threats that may jeopardize the organizational sustainability and pressure them to find effective ways to survive and develop. The recent COVID-19 health emergency confirmed the unpredictability of some events that may have a significant impact on the life of enterprises, damaging the management of a company and interrupting its continuity in the flow of activities with consequences for companies’ profitability. Learning to live with uncertainty, abandoning the notion of stability, expecting the unexpected, and increasing the capability to learn from crisis is crucial to survive in such a complex and volatile environment. This paper presents a systematic scoping review with the aim to identify, analyze and underline the importance of having a conceptual framework designed to develop and improve the risk and resilience for organizations, in particular during times of crisis. In the aftermath of COVID-19 is of paramount importance to adopt a complete new and refreshing approach which could enable a firm to more fully realize the benefits that changing opportunities present.

Aylan Kurdi’den Sonra: Sanatta Göçün Kaydı

Binlerce yıl öncesinde yaşam biçimi olan göçebelik, bireylerin ve toplumların hayatını şekillendiren bir fiil olarak karşımıza çıkmaktadır. Neolitik devrimle yerleşik düzene geçen insanoğlu temel barınma ve beslenme ihtiyaçlarını karşılayabildiği alanlarda hayatlarına devam etmiştir; ancak göç hareketleri son bulmamış ve çağlar boyunca kültürlerarası etkileşime katkı yapmaya devam etmiştir. Tercih sonucu ya da zorunlu bir fiil olan göç; bireysel ve toplumsal düzeyde birçok farklı etki yarattığı gibi sanat alanında da birtakım yansımalar ve etkiler ile karşımıza çıkmaktadır. Göç ve göçmenlik kavramları üzerinden kişisel fikirlerini farklı disiplinler aracılığı ile izleyiciye aktaran sanatçılar, kendi deneyimlerini ya da göç ile sonuçlanmış savaşlar, afetler, açlık gibi toplum belleğinde yer edinmiş birçok olay veya durumu ele alarak incelemiştir. Sinema, edebiyat ve tiyatro gibi çeşitli alanlarda nesne edinilen göç; plastik sanatlar alanında da sıklıkla kullanılmaktadır. Dünya toplumu birçok göç hareketine ve buna bağlı olarak birçok trajediye şahitlik etmiştir ancak; yaşanan bazı olaylar büyük çapta etkiler yaratmıştır. Aylan Kurdi ve ailesinin 2015 yılında çıktığı göç yolunda trajik biçimde hayatlarını kaybetmesi de yakın zamanda yaşanan büyük trajedilerden biridir ve bu çalışmada Aylan Kurdi üzerinden işlenerek, göç teması etrafında şekillenen sanat eserleri incelenmiş, yaşanan olayın plastik sanatlara yansımaları Ai Weiwei, Banksy, Pekka Jylhä gibi seçilmiş sanatçıların yapıtları özelinde değerlendirilmiştir.

Evaluation Of Histological Changes In Kidney Of Male Albino Rats Treated With Silver Nanoparticles

The wide uses of silver nanoparticles in the industrial, medical and cosmetic fields with it ease of entry into human body and absorption by gastrointestinal tract there for designed this study to find out the effect of silver nanoparticles on the tissue structure and functional performance of the kidney, because the process of filtering blood takes place widely in the kidney. 24 male albino rats were used for the experimental study, the rats were divided into three groups, first groups(control) dosage with normal saline solution (Injected intraperitoneal), second group (treatment) dosage with AgNPs0.75mg/kg of body weight and third group (treatment) dosage with AgNPs 1.5mg/kg of body weight. Each concentration of AgNP was dissolved in1ml of normal saline and all experimental male rats were injected via intraperitoneal with single dose /day for30 days. The resultsin this study showed tissue damage in the kidney such as vacuolar and fatty degeneration in renal tubules with pyknic nucleus in glomerulus also appear massive aggregation of mononuclear cells around blood vessels with hemorrhage and hemosiderin in renal tubules with occurrence the amyloid inside the blood vessels with necrosis in different cells associated with malfunction of kidney Shown in significant difference in urea, uric acid and creatinine when compare with control group. Histopathological changes associated with the dysfunction of the kidneys due to the effect of nanoparticles directly on the cells such as the occurrence of the reactive oxygen species (ROS) generation has key role in the events of structural and functional disorders in the kidney of male albino rats.

Represent Human Digestive System By Using RAD Business Process Models

Through the above topic and studies, it appears that there is a novel approach to using business process models to represent the human digestive system. The proposed approach adopted, expanding the role activity diagram notation (RAD) to bridge the gap between business process models and human digestive systems, we show how to analyze, the human digestive system can be applied and evaluated on the process model, developed using the role activity diagram to activate the required quality, more clearly in the model . This gives a useful extension of modeling methods similar to RAD, in addition to providing a basis for improving the business of various commercial enterprises, according to RAD, it is clear that any business is not far from any biological system, as the first step in the project act is approval of the project, a library for example And the same is true for the digestive system and the related things between this and the progressive system and work have evolved within the commercial enterprises (Role-Activity Diagram (RAD), The objectives required in the research have been verified as to know the similarities between commercial and vital organs, and the possibility of representing A complete vital member by RAD, and easy understanding of the mechanism necessary for business for businessmen, and the digestive system has been more accurately identified, its mechanism of action, its apparatus and its usefulness, and this is what is required to be proven in the events of this study.

Left Atrial Thrombus Mimicking Myxoma Secondary to Rebound Hypercoagulable State

Novel oral anticoagulants (NOACs) have made the use of anticoagulation in patients with atrial fibrillation (AFib) much more convenient and predictable. It is a very common practice to hold anticoagulation either in anticipation of surgical procedures (to prevent excessive bleeding) or in case of acute bleeding episodes. This abrupt withdrawal of anticoagulation tilts the balance in favor of pro-thrombotic state in the body. We present a case of a 60-year-old man with past medical history of AFib who abruptly discontinued his apixaban (Eliquis). This patient presented to emergency room with the complaint of weakness and numbness of left arm and left half of the face. Stroke code was activated, and patient received tissue plasminogen activator (t-PA). This resulted in significant improvement of symptoms within hours of receiving treatment. Later during the same day, patient developed numbness and tingling of fingers of left hand. On physical exam, left hand was cold to touch and radial pulse was absent. Arterial duplex revealed occluded ulnar and radial arteries. Vascular surgery performed embolectomy to establish blood flow in the radial and ulnar arteries. Transthoracic echocardiogram revealed large left atrial mass attached to the atrial septum. Most likely t-PA infusion in the setting of atrial mass led to distal showering of emboli resulting in stenosis of radial and ulnar arteries. The left atrial mass was most likely thrombus as patient had cardiac imaging including transthoracic echocardiogram and computed tomography of heart prior to these events which did not reveal any mass in left atrium. In short, as clinicians we should be aware of the hypercoagulability associated with withdrawal of anticoagulation. In addition, we should be wary of the challenges associated with differentiating cardiac masses of different etiology. J Med Cases. 2021;12(6):243-247 doi: https://doi.org/10.14740/jmc3656

Large Vessel Stroke Following Multiple Other Strokes and Cardiomyopathy in a Forty-Nine-Year-Old COVID-19 Patient

The novel coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has made its presence known on the centerstage of worldwide healthcare in 2020. Although it is widely known about its pulmonary presence and ensuing complications, evidence is emerging that there are other organ systems including the cardiovascular and cerebrovascular systems that may be damaged by this virus. There have been reports of large vessel stroke occurring in coronavirus disease 2019 (COVID-19) positive patients, with very few reported in the age group less than 50 years. In this case, we describe a previously healthy 49-year-old male who presented with signs of stroke, and was found to have the novel coronavirus as he had been suffering from upper respiratory tract symptoms for 3 weeks. He subsequently developed further large vessel stroke while in the hospital despite being started on antiplatelet therapy. He was also found to have new onset cardiomyopathy. He was started on anticoagulation and discharged with follow-up for cardiomyopathy testing outpatient. This case begs the question on which anticoagulation to utilize in COVID-19 positive patients to be effective in preventing thrombotic events. It is postulated that a pro-inflammatory state induced by the virus and the virus’ affinity for angiotensin converting enzyme-2 receptors in the cerebral vasculature are predispositions to cause a stroke. The virus also directly damages cardiac myocytes causing a number of cardiac complications including cardiomyopathy. It is crucial that guidelines on anticoagulation choice and indications for when to start anticoagulation be developed in order to prevent the more devastating consequences of thrombosis and embolism and their subsequent clinical sequelae.

Variance Inflation Due to Censoring in Survival Probability Estimates

One of the most obvious features of time-to-event data is the occurrence of censoring. Rarely, if ever, studies are conducted until all participants experience the event of interest. Some participants survive beyond the end of follow-up time, some drop out from the studies for various non-study related reasons. During research planning it is paramount to consider the effect of censoring the follow-up times on the estimates. Herein, we look into the possibility of assessingthe loss of information, as measured by the variability of the survival probability estimates under right censoring. We provide the researchers with an easy to use formula to assess the magnitude of variance inflation due to censoring. Additionally, we conducted simulation studies assuming various survival distributions. We conclude that the provided variance inflation estimator can be an accurate practical tool for applied statisticians.
