Elegy to an Oz Republic: First Steps in a Ceremony of Invocation towards Reconciliation

In 2012 the author completed a series of drawings that, while figurative in form, were structurally based on and derived their inspiration from Robert Motherwell’s abstract series, Elegies to the Spanish Republic (1963-1975). This wholesale 'borrowing', 'quotation' and 'citation' raises the questions addressed in this article. What does it mean to engage in acts of appropriation now? And, more importantly, can such acts of appropriation draw on the spirit of the 'original' work to make a (political) difference? 

Environmental Education in the Public Sphere: Comparing Practice with Psychosocial Determinants of Behavior and Societal Change

Environmental education of the general public is widely practiced by a variety of types of organizations. Dedicated environmental groups, nature centers, zoos, parks, and other entities work on issues ranging from local threats to air, water, and habitat to global problems such as climate change and deforestation. A great deal of those efforts focus largely on providing information and raising awareness. Behavioral research and change models, however, suggest other factors are important in order to effect change on an individual, regional, or societal level. An analysis of environmental education in practice, examining methods and materials in use, showed the degree to which there were alignments between the content and psychosocial determinants of change, as well as how actions related to change theories. This mixed-methods study of groups doing environmental education in the public sphere compared their practices with the factors shown to help predict pro-environmental behavior, why people change their actions and habits. Through this survey research and multiple case study, increased knowledge and understanding can help inform future efforts at change on critical local, national, and world environmental problems. It can also lead to further research into environmental education, using behavior and change theories

The brachyopoid Hadrokkosaurus bradyi from the early Middle Triassic of Arizona, and a phylogenetic analysis of lower jaw characters in temnospondyl amphibians

The holotype of the brachyopoid temnospondyl Hadrokkosaurus bradyi, represented by a right lower jaw ramus, is re−ex− amined based upon new data and revision of various morphological features. Additional fragmentary jaw material re− ferred to this species is briefly described. Prominent features are a large postsymphyseal foramen that is anteriorly open, and prearticular and surangular buttresses for support of the articular. Brachyopoid characters include a long and robust postglenoid area formed by surangular and prearticular, anterior and posterior keels on at least some marginal dentary teeth, and subtriangular outline of the adductor fossa in dorsal view. Five features of the holotype ramus, long thought to be at odds with its brachyopoid or temnospondyl nature, are critically re−evaluated. A phylogenetic analysis of lower jaw characters in temnospondyls retrieves most of the clades found in more comprehensive data sets, but the statistical node support is low. Brachyopoids are monophyletic, with Hadrokkosaurus emerging as their most basal taxon

Payment network scale economies, SEPA, and cash replacement

The goal of SEPA (Single Euro Payments Area) is to facilitate the emergence of a competitive, intra-European market by making cross-border payments as easy as domestic transactions. With crossborder inter-operability for electronic payments, card transactions will increasingly replace cash and checks for all types of payments. Using different methods, the authors estimate card and other payment network scale economies for Europe. These indicate substantial cost efficiency gains if processing is consolidated across borders rather than "piggybacked" onto existing national operations. Cost reductions likely to induce greater replacement of small value cash transactions are also illustrated.

Economics of payment cards: a status report

This article surveys the recent theoretical literature on payment cards (focusing on debit and credit cards) and studies this research's possible implications for the current public policy debate over payment card networks and the pricing of their services for both consumers and merchants.Payment systems ; Credit cards

Consumer choice and merchant acceptance of payment media

We study the ability of banks and merchants to influence the consumer's payment instrument choice. Consumers participate in payment card networks to insure themselves against three types of shocks -- income, theft, and their merchant match. Merchants choose which payment instruments to accept based on their production costs and increased profit opportunities. Our key results can be summarized as follows. The structure of prices is determined by the level of the bank's cost to provide payment services including the level of aggregate credit loss, the probability of theft, and the timing of income inflows. We also identify equilibria where the bank finds it profitable to offer one or both payment cards. Our model predicts that when merchants are restricted to charging a uniform price for goods that they sell, the bank benefits while consumers and merchants are worse off. Finally, we compare welfare-maximizing price structures to those that result from the bank's profit-maximizing price structure.Payment systems ; Credit cards ; Consumer credit
