Modern Money Theory: A Critical Assessment and a Proposal for the State As Innovator of First Resort
No full textModern Money Theory (MMT) describes the functioning of a pure credit economy, assuming that the state can finance public spending via monetisation on the part of the central bank: in this light MMT proponents maintain that taxation and bond issues are irrelevant to public deficit financing. Another feature peculiar to MMT is the belief that expansionary fiscal policies can guarantee full employment in a condition where the state acts as an employer of last resort (ELR). The aim of this paper is threefold: (a) to understand and rationalise the logical framework of MMT (Section 2.1); (b) to address some of the controversial issues of this approach, with particular regard to the ELR programme proposal and to the actual role played by taxation and bonds in public deficit financing (Section 2.2); (c) to propose an extension of the ELR programme, arguing that it can be used for the application of innovations by the state (Section Three)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Cystic adventitial disease of the popliteal artery—a pictorial, clinical, and pathological study of a case
No full textWe report on a case of severe cystic adventitial disease involving the popliteal artery in a man aged 42, who in 2009 underwent surgical resection of the cyst and the tract of the involved artery. The arterial reconstruction was then performed with an autogenous graft, using a reversed small saphenous vein interposition. The surgical specimen was histologically examined. The postoperative course was uneventful, and the patient was discharged on the 8th day. Currently, on an 11-year long clinical follow-up, the patient is healthy, and the graft is patent. A pictorial essay of the clinical and pathological findings of the case is presented, along with a brief discussion covering the main issues relevant to the disease manifestations and diagnosis, clinical differential diagnoses, and the treatment options. The pertinent world literature has been reviewed as well
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

No full textEndovascular repair of an abdominal aortic aneurysm associated with crossed fused renal ectopia
Full text linkChimney/snorkel endovascular aneurysm repair (Ch-EVAR) enables the minimally invasive treatment of abdominal aortic aneurysm in anatomically challenging and high-risk surgical cases. Here, we present the case of a 77-year-old man with an abdominal aortic aneurysm associated with crossed fused renal ectopia and an ectopic renal artery arising directly from the aneurysm sac. After successful implementation of Ch-EVAR, computed tomography angiography at 18 months revealed no endoleaks, patency of the parallel graft, and normal renal vascularization and function. This report underscores the feasibility of Ch-EVAR in a case with high anatomic complexity
