Purpose The economic system of competitive capitalism strives toward liquid markets wherein the cost for transacting is minimized. Liquidity is mostly addressed in association with abstract markets (e.g. the securities market), but also consumer markets are determined by liquidity concerns. The purpose of this paper is to examine the shopping mall concept, developed by the architect and social reformer Victor Gruen during the early 1950s, as a form of production of capitalist space, intended to reduce transaction costs. As an auxiliary benefit, Gruen envisioned the shopping mall as a cultural and civic center in the midst of the satellite town of suburbia, the new site of urban expansion during the post-war boom decades. Design/methodology/approach The paper reviews secondary literature on the historical development of the shopping mall as a consumer space. In addition, relevant economic and social science literature is referenced. Findings The architecture, design, ornamentation and day-to-day management of the shopping mall were premised on a consumerist way of life, ultimately serving as an all-too-visual index of the triumph of competitive capitalism in the cold war era. However, Gruen’s accomplishments were gradually compromised by the interest of money-minded developers and construction industry actors, and the shopping mall arguably never fulfilled the social and cultural function that Gruen anticipated. Regardless of such outcomes, the production of capitalist space as scripted by Gruen is still determining everyday life in consumer society, making Gruen a key figure, albeit only limitedly recognized, in the history of late modern society and in the capitalist economy. Originality/value The paper emphasizes the role of Victor Gruen in the post-Second World War period, being one of the most influential practitioners and social reformers in the era. Furthermore, the paper stresses how market liquidity is a key concern in Gruen’s project to create a communal space for the American suburban population in the era of the expanding welfare state.

Photographs and optical images, whatever their contents, are imprints of the electromagnetic waves in the (human) visible range of wavelengths, we refer to as light. Furthermore, they are designed to portray different parts of the visible light in terms of different colours, in analogy with the human eyes, however imperfectly. The world outside our eyes and cameras, however, is permeated by electromagnetic waves with much wider spectrum of wavelengths than those in the visible range. Importantly also, colour is a construct of our eye–brains: the Universe itself has no colour, independently of us. I ask how does the knowledge of these facts change the way we perceive the colour in optical images and photographs, whatever their relationship to the world in a representational sense may be? By employing three images, with very different origins and vistas – one a direct photograph, the other two synthetically constructed images using real cosmological observations – I demonstrate the extent to which colour in such images can hide the underlying phenomena of which they claim to visually speak, both due to its nature as a coarse-grained visual index, and by being restricted to the visible range. The aim is not to belittle the important role that our (restricted) vision together with our perception of colour have played in the evolution of our species, and still play in the way we relate to the world informationally, aesthetically and emotionally. But rather to show that recognizing the limitations of our vision and complementing it with the knowledge of the phenomena underlying optical images and photographs can allow us to perceive them anew and provide additional tools (both conceptual and visual) to imagine and envision such images outside the bounds of the visible range and colour.

Brentano was a philosopher and psychologist who taught at the Universities of Würzburg and Vienna. He made significant contributions to almost every branch of philosophy, notably psychology and philosophy of mind, ontology, ethics and the philosophy of language. He also published several books on the history of philosophy, especially Aristotle, and contended that philosophy proceeds in cycles of advance and decline. He is best known for reintroducing the scholastic concept of intentionality into philosophy and proclaiming it as the characteristic mark of the mental. His teachings, especially those on what he called descriptive psychology, influenced the phenomenological movement in the twentieth century, but because of his concern for precise statement and his sensitivity to the dangers of the undisciplined use of philosophical language, his work also bears affinities to analytic philosophy. His anti-speculative conception of philosophy as a rigorous discipline was furthered by his many brilliant students. Late in life Brentano’s philosophy radically changed: he advocated a sparse ontology of physical and mental things (reism), coupled with a linguistic fictionalism stating that all language purportedly referring to non-things can be replaced by language referring only to things.

Abstract Background Visual inspection is the most widespread method for evaluating sample hemolysis in hemostasis laboratories. The hemolysis index (HI) was determined visually (visual index, VI) and measured on an ACL TOP 750 (IL Werfen) system with a hemolysis-icterus-lipemia index (HIL) module. These values were compared with those measured on clinical chemistry systems Unicel DXC600 and AU680 and with quantitation of free-hemoglobin (Hb) performed by a spectrophotometric measurement method (SMM). Methods The HI was measured in 356 sodium citrate plasma samples, 306 of which were visibly hemolyzed to varying degrees and 50 were not hemolyzed. The analytical performance of each method was evaluated. Results Linear regression analysis, calculated between SMM and the other systems in the study, returned coefficients of determination r2 = 0.853 (AU680), r2 = 0.893 (DXC600) and r2 = 0.917 (ACL TOP 750). An r2 = 0.648 was obtained for linear regression analysis between VI and ACL TOP 750. In addition, ACL TOP 750 showed an excellent correlation in multivariate analysis (r2 = 0.958), showing good sensitivity (0.939) and specificity (0.934) and a diagnostic accuracy of 94%. By comparison, DXC600 and AU680 showed coefficients of determination of 0.945 and 0.923, respectively. A cut-off was set at 0.15 g/L free-Hb, as determined by the automated method, such that any hemostasis samples measuring above this threshold should not be analyzed. Based on this criterion, samples were classified as accepted or rejected, and the number of samples discarded during VI or ACL TOP 750 measurements was compared. Conclusions This study confirmed that hemostasis laboratories should consider introducing an objective, automated and standardized method to check samples for hemolysis. By relying solely on visual inspection, up to 50% of samples could be unnecessarily rejected. The ACL TOP 750 system demonstrated a satisfactory analytical performance, giving results comparable to those of the reference method.
