The irrelevance of methodology and the art of the possible: Reading Sen and Hirschman
No full textEconomic methodologists have observed that economists do not practice what they think their methodology is. Two positions follow from this. One insists on the need for `better' practice in maintaining `scientific' standard, while the other takes the literary turn. Following the second route we argue that appraisal of economic theories cannot be done by applying a general `scientific method' apart from practice. Methodological conversations, which are shaped by various strategies taken by practitioners to persuade each other, can only be studied and improved by reading the most persuasive of the authors in the discipline. Writings of Albert Hirschman and Amartya Sen are chosen to be read following our approach.Methodology, positivism, rhetoric, methodological conversation, internal criticism
Incidence and Natural History of Isolated Abdominal Aortic Dissection: A Population Based Assessment From 1995-2015
No full textBackground: Isolated abdominal dissection (IAD) is an uncommon clinical problem that is less well understood than thoracic aortic dissection. We performed a population based assessment of the incidence, natural history and treatment outcomes of IAD to better characterize this disease.
Methods: We utilized the Rochester Epidemiology Project to identify all Olmsted County, MN residents with a diagnosis of aortic dissection, intramural hematoma or penetrating ulcer (1995-2015). Diagnostic imaging of all patients was reviewed to confirm the diagnosis of IAD for inclusion. Presentation, treatment, and outcomes were reviewed. Survival of IAD patients was compared to age- and sex-matched population controls 3:1.
Results: Of 133 residents with aortic syndrome (aortic dissection, intramural hematoma, or penetrating ulcer), 23 were initially diagnosed with IAD. Nine were reclassified as PAU and excluded, leaving 14 patients for review (10 male (71%), mean age 71 years). Three patients (21%) were symptomatic (abdominal/back pain/ hypertension) and none had malperfusion/rupture. Prior aortic dilatation was present in 8 (57%) and Marfan syndrome in 1 (7%). Two (14%) patients had iatrogenic IAD. Initial management was medical in 13 and EVAR in one (symptomatic subacute, infrarenal dissection with small aneurysm). The median clinical and imaging follow-up was 6.7 (range 0-17 years). An abdominal aortic aneurysm occurred in 8 (6 at the time of IAD diagnosis, one at 2.9 years, and one at 5.2 years after diagnosis). The average growth in the entire cohort was 0.9+0.4 cm, which translated to an average growth rate of 0.09 cm/year. Subsequent intervention was performed in 2; for severe aortic stenosis with claudication in one (infrarenal aortic stenting) and increasing aortic size in one (open repair). One patient required re-intervention (thrombolysis and stenting for EVAR limb thrombosis). Survival for IAD at 1, 3, and 5 years was 93%, 85% and 76% compared with population controls at 98%, 85% and 71% respectively (long rank p= 0.38). Mortality was due to cardiovascular causes in 3 (21%) and no deaths were aortic related. Major adverse cardiac events occurred in 5 (36%) due to heart failure.
Conclusions: Isolated abdominal dissection is rare. Initial management for asymptomatic patients is medical. The aortic growth rate is slow, with no aortic related mortality and a low rate of aortic intervention. Overall mortality is similar to population controls. Heart failure and cardiac related death are prevalent, suggesting close cardiovascular care is needed in this patient population

The Contributions of Professor Amartya Sen in the Field of Human Rights
No full textThis paper analyses the work of the Nobel Prize winning economist Professor Amartya Sen from the perspective of human rights. It assesses the ways in which Sen's research agenda has deepened and expanded human rights discourse in the disciplines of ethics and economics, and examines how his work has promoted cross-fertilisation and integration on this subject across traditional disciplinary divides. The paper suggests that Sen's development of a 'scholarly bridge' between human rights and economics is an important and innovative contribution that has methodological as well as substantive importance and that provides a prototype and stimuli for future research. It also establishes that the idea of fundamental freedoms and human rights is itself an important gateway into understanding the nature, scope and significance of Sen's research. The paper concludes with a brief assessment of the challenges to be addressed in taking Sen's contributions in the field of human rights forward.Amartya Sen, human rights, poverty, freedom, obligation, capability approach, meta-rights, entitlements, opportunity freedom, liberty-rights

Vascular Surgery and Robotics
No full textThe application of robotics to Vascular surgery has not progressed as rapidly as of endovascular technology, but this is changing with the amalgamation of these two fields. The advent of Endovascular robotics is an exciting field which overcomes many of the limitations of endovascular therapy like vessel tortuosity and operator fatigue. This has much clinical appeal for the surgeon and hold significant promise of better patient outcomes. As with most newer technological advances, it is still limited by cost and availability. However, this field has seen some rapid progress in the last decade with the technology moving into the clinical realm. This review details the development of robotics, applications, outcomes, advantages, disadvantages and current advances focussing on Vascular and Endovascular robotic
OVERCOMING POSITIVISM IN ECONOMICS: AMARTYA SEN'S PROJECT OF INFUSING ETHICS INTO ECONOMICS
No full textLogical Positivism, which arose in philosophy early in the twentieth century, proclaimed the sharp distinction between facts and values. Despite objections at the time, positivism was imported into economics in the 1930s. Over time, objections lessened; economics was transformed and ethical considerations were driven out of its core. In the 1950s, debates about positivism arose within the discipline which had exported it. According to the American philosopher Hilary Putnam, the fact/value distinction is now discredited in philosophy. If that is so, the methodological foundations of contemporary economics are also discredited. In this article I examine Amartya Sen’s moral science of economics. First, I will present his historical account of the connections between economics and ethics. Sen claims that there was a close connection between the two until positivism was imported. Second, I will sketch some of Sen’s ethical objections to modern economics, which is still suffering from positivism. Finally, I will lay out some of his ideas on how economics can be returned to an ethical path. Once the ground has been cleared of positivism, ethics can re-emerge in economics in various ways. One path has been marked out by Sen.Teaching/Communication/Extension/Profession,
