Can Margin Differences in Vertical Marketing Channels Lead to Contracts with Slotting Fees?
Authors: Dhar Tirtha 
Published: July 2013

In this paper, we show that slotting fees can be part of an equilibrium solution if per-unit downstream margin is smaller than the per-unit upstream margin. In recent literature, a similar margin-based argument is made by Klein and Wright (2007), whereas intense downstream retail competition coupled with high upstream margin causes upstream manufacturers to offer slotting fees for promotional shelf space. In this paper, we generalize this argument and show that it is possible to have the margin-based argument without any downstream retail competition and competition between products within a retail chain. Interestingly we show that slotting fees will be larger if the products sold by a retailer are complements rather than substitutes. Using a model of a channel bargaining game, we also provide the necessary and sufficient conditions for the existence of slotting fees and show that for contracts with slotting fees under full vertical coordination, upstream marginal cost functions need to be increasing. Broadly, our findings provide new insights into the strategic role of downstream product assortment on equilibrium-marketing-channel contracts with slotting fees. This paper was accepted by J.

Simultaneous vs. Sequential Group-Buying Mechanisms
Authors: Hu Ming , Shi Mengze , Wu Jiahua 
Published: July 2013

This paper studies the design of group-buying mechanisms in a two-period game where cohorts of consumers arrive at a deal and make sign-up decisions sequentially. A firm can adopt either a sequential mechanism where the firm discloses to second-period arrivals the number of sign-ups accumulated in the first period, or a simultaneous mechanism where the firm does not post the number of first-period sign-ups and hence each cohort of consumers faces uncertainty about another cohort's size and valuations when making sign-up decisions. Our analysis shows that, compared with the simultaneous mechanism, the sequential mechanism leads to higher deal success rates and larger expected consumer surpluses. This result holds for a multiperiod extension and when the firm offers a price discount schedule with multiple breakpoints. Finally, when the firm can manage the sequence of arrivals, it should inform the smaller cohort of consumers first. This paper was accepted by J. Miguel Villas-Boas, marketing.
A Person–Organization Discontinuity in Contract Perception: Why Corporations Can Get Away with Breaking Contracts But Individuals Cannot
Authors: Haran Uriel 
Published: July 2013

Most legal systems in the world follow the principle of corporate personhood, which grants organizations the same legal status as natural persons. Although debate over the notion of corporate personhood has been fierce, whether and how this principle is applied in people's beliefs and intuitions has yet to be empirically examined. This work addresses the gap in the literature, in the context of formal contracts. While contracts are typically seen as either morally binding promises or morally neutral business instruments, the data presented here show that contracts of individuals are associated more strongly with promises than are contracts of organizations. As a result, breach of contract by an individual is seen as a moral transgression. The same behavior by an organization, however, is viewed more as a legitimate business decision. This paper also finds that contractual obligations should be phrased in “promise” terms to eliminate this person–organization discontinuity.

Supermodularity and Affine Policies in Dynamic Robust Optimization
Authors: Iancu Dan A. , Sharma Mayank , Sviridenko Maxim 
Published: July 2013

This paper considers a particular class of dynamic robust optimization problems, where a large number of decisions must be made in the first stage, which consequently fix the constraints and cost structure underlying a one-dimensional, linear dynamical system. We seek to bridge two classical paradigms for solving such problems, namely, (1) dynamic programming (DP), and (2) policies parameterized in model uncertainties (also known as decision rules), obtained by solving tractable convex optimization problems. We show that if the uncertainty sets are integer sublattices of the unit hypercube, the DP value functions are convex and supermodular in the uncertain parameters, and a certain technical condition is satisfied, then decision rules that are affine in the uncertain parameters are optimal. We also derive conditions under which such rules can be obtained by optimizing simple (i.e., linear) objective functions over the uncertainty sets. Our results suggest new modeling paradigms for dynamic robust optimization, and our proofs, which bring together ideas from three areas of optimization typically studied separately—robust optimization, combinatorial optimization (the theory of lattice programming and supermodularity), and global optimization (the theory of concave envelopes)—may be of independent interest. We exemplify our findings in a class of applications concerning the design of flexible production processes, where a retailer seeks to optimally compute a set of strategic decisions (before the start of a selling season), as well as in-season replenishment policies. We show that, when the costs incurred are jointly convex, replenishment policies that depend linearly on the realized demands are optimal. When the costs are also piecewise affine, all the optimal decisions can be found by solving a single linear program of small size (when all decisions are continuous) or a mixed-integer, linear program of the same size (when some strategic decisions are discrete).
An Infinite Server System with General Packing Constraints
Authors: Stolyar Alexander L. 
Published: July 2013

We consider a service system model primarily motivated by the problem of efficient assignment of virtual machines to physical host machines in a network cloud, so that the number of occupied hosts is minimized. There are multiple input flows of different type customers, with a customer mean service time depending on its type. There is an infinite number of servers. A server-packing configuration is the vector k = {ki}, where ki is the number of type i customers the server “contains.” Packing constraints must be observed; namely, there is a fixed finite set of configurations k that are allowed. Service times of different customers are independent; after a service completion, each customer leaves its server and the system. Each new arriving customer is placed for service immediately; it can be placed into a server already serving other customers (as long as packing constraints are not violated), or into an idle server. We consider a simple parsimonious real-time algorithm, called Greedy, that attempts to minimize the increment of the objective function [Formula: see text], α > 0, caused by each new assignment; here Xk is the number of servers in configuration k. (When α is small, [Formula: see text] approximates the total number [Formula: see text] of occupied servers.) Our main results show that certain versions of the Greedy algorithm are asymptotically optimal, in the sense of minimizing [Formula: see text] in stationary regime as the input flow rates grow to infinity. We also show that in the special case when the set of allowed configurations is determined by vector-packing constraints, the Greedy algorithm can work with aggregate configurations as opposed to exact configurations k, thus reducing computational complexity while preserving the asymptotic optimality.
Bridging divides: Transference in the work of Lynne Heller
Authors: Hare Anastasia 
Published: July 2013

Abstract
This article discusses the work of Canadian artist Lynne Heller, specifically her project The Adventures of Nar Duell in Second Life begun in 2007. It examines her use of computational arts to blur distinctions between artistic media through the creation of digital and material composites in both physical and virtual spaces. Heller’s performances, which involve creating and navigating an avatar in Second Life, become material for her comic books and immersive, multimedia art installations. Moving in and out of formats, Heller bridges physical and alternative spaces and identities. An interview with the artist details the development of her multifaceted project and aesthetic complexity, particularly her artistic strategies and the ideas that inform her work, such as transference and the relationship with her avatar described as a mother-daughter bond. This article considers the implications of crafting within the virtual, and addresses aspects of materiality within these spaces, as well as modes of viewing, interaction and collaboration.
The low life epic: The Adventures of Nar Duell in Second Life
Authors: Heller Lynne 
Published: July 2013

Abstract
In this comic book style adventure, Lynne Heller’s intrepid but naive avatar, Nar Duell explores her world. The translation of the virtual adventures into comix style documentation is a natural expression of the experience of spending time in Second Life. The superficial and arbitrary nature of virtual life is mirrored in the ‘pow, bam, zap’ aesthetic of the printed page. Nar Duell’s adventures are transmogrified into narrative. The graphic novel supports the illusive nature of the work with the concrete and historical reference to print – a travel guide, and captures the essence and detail of what has been deemed alien and exotic by the outside world, and makes intimate that which is generally seen as inaccessible.
The actor, the designer and digital media: A case study at Formello
Authors: Zellner Dan 
Published: July 2013

Abstract
An account, from a performer’s perspective, of the REMAP/RITL workshop in Italy that details the various performer/media relationships encountered during the workshop. These experiences are identified using David Saltz’s taxonomy of performer/media relationships and described in the context of improvisational theatre and traditional Commedia dell’Arte mask work. Three digital media aspects of the work (‘the field’, ‘the object’ and ‘the mask’) are explored and conclusions drawn regarding approaches to digital media and areas for further research.
An intimate appearance: Black Box Production in the twenty-first century
Authors: Steck Rachel Kinsman 
Published: July 2013

Abstract
This article explores how, in an era where e-mail has discharged the letter or where Facebook replaces face-time with friends over a drink, where the lines between virtual reality and reality are colliding, can live performance aid in the creation of an activated citizenship? I believe to create an activated citizenship, we must first involve an activated spectatorship. Wrapped up in spectatorship, itself, are the elements of identity politics, subjectivity, ways of looking/seeing/gazing and cultural conventions. This research explores the relationship between the ways in which spectators look/see/view and the ways in which the production, working with the intimate relationship of performance-spectatorship in a black box theatre, manipulates the visual vocabulary, collapsing the boundaries of culture, performance and the real.
Lighting – A part of a changing aesthetics
Authors: White Christine 
Published: July 2013

Abstract
The advancements in, and the use of technology within, the theatre have resulted in some changes in directorial practice. As these advances in technology have changed the emphasis of the process of production, the prominence given to the director as sole ‘auteur’ of a piece of work has become diminished. The scenographic team is now more legitimately described as the ‘auteurs’ of a production. Another contributory factor for these developments has been the changes in theatre practice influenced both by European and Eastern European performance theories. This article explores the nature of these changes and influences and discusses the technology, which has offered greater scope for the manipulation of the stage image, in particular the use of lighting in scenography. The director is no longer a specialist in every area, ‘a man of the theatre’. He or she works collaboratively with the other artists in the production team in a much more democratic process of production. More than at any other time, the director works as another member of the team not only because he or she lacks knowledge, but because the technology has allowed considerable flexibility and the director’s ‘vision’ can be translated into many forms, materials and theories. The contribution of scenography to these changes, changes in acting styles and of what is expected within a performance space, has transformed the way in which an actor uses that space.
For example, the importance that Brecht placed on Caspar Neher’s designs for a cohesive performance structure (based on his sketches of/for the rehearsal process) and the relation of the actor to light (which Appia recognized as important) has resulted in stage technologies and scenography emerging as a partner of the actor and thus a new aesthetic.
The Stage is Set – or is it? – Production by Chris White, Derby Theatre, 20 March 2013
Authors: White Christine 
Published: July 2013

Abstract
The aim of the production was to perform the lighting research juxtaposing the historical research with special effects and lighting techniques. It experimented with performance and lighting styles to demonstrate the use of imagination and suggestion, and the emblematic and non-naturalistic in lighting effects from the Renaissance through to the interconnectedness of animation and live performance technologies.
Dynamic scores: Extending the parameter space of live performance
Authors: Sayer Tim 
Published: July 2013

Abstract
This article describes the rationale behind the development of a digital performance system that enables a musical ensemble or solo instrumentalist to interact with a generative and reactive visual score, projected in a cinematic environment. A partial feedback loop is setup between the performer and a projection of visual media, which allow the performer to perceive a response to their playing in certain aspects of the projection. The premise underpinning this piece runs far deeper than merely allowing acoustic instruments to interact with technology; it builds on the pioneering work of Benjamin Libet (1916–2007) and challenges the notion of volition and agency in the way performers react and respond to visual stimulus. The performances enabled by this system will not only provide an audience with a stimulating cinematic event but will also provoke the performers to engage in new and unexpected modes of musical behaviour. A prototype of this system is evaluated as a means of developing psychological and philosophical themes around the notion of freewill in interactive audio-visual performance.
‘Your Attention Please’: Media, spectacle and The Complex
Authors: Luber Steve 
Published: July 2013

Abstract
This article explores the problematic concept of attention in a mediatized culture. Using Blue Man Group (BMG)’s The Complex concert as a case study, I historicize and analyse discourse on attention and perception through phenomenological and deconstructive frames. I conclude with Michel Foucault’s conception of the heterotopia as the site for a productive analysis of The Complex show, a mediatized manifestation of other spaces, ones that defy focused attention and reveal encounters with and misfires from contemporary media consumption. The heterotopic multimedia concert calls the possibility of attention into question, and with this challenge the Blue Man provides a constructive re-evaluation of consumption and media culture.
The national culture references on the drama costumes: Are there limits?
Authors: Rocha Rosane Muniz 
Published: July 2013

Abstract
The purpose of this article is to analyse the use of local references in drama costume design, considering the possible limits when ‘showing yourself’ to others. From crossovers between the languages of Carnival and theatre, it brings up a local issue, but one that demands a global reflection, because it can lead any one of us, with any cultural background, from any country, to think about which references to choose and how to use them in drama costume design.
Beyond the gallery: The human foot as masterpiece of engineering, a work of art and window on our health
Authors: Oddey Alison 
Published: July 2013

Abstract
In this article, I want to examine the origins of my research, how the research process developed into an experiment of sorts, reflecting on that process and citing it as a potential hybridized form of cultural health interactive art exhibition event, focussing on the feet as they relate to health and well-being for public health engagement. In creating this unique live event, I wanted to interrogate, whether a cultural health intervention in an art gallery, can provide an alternative means to generate and promote public health awareness of self-preventive health care for self-help, wellness and well-being. I will discuss the feasibility of this type of health intervention, arguing that there is a need for these types of interventions to improve health through art, which can respond to local need within a community and bring about behaviour change.
I will explore how art can cause us to reflect on health, to understand how feet can have pressure points that affect well-being, and how art can enable people to reflect on health images and think about their own self-care and lifestyle choices. I will analyse how the human foot as masterpiece of engineering and art experience can affect people’s health, and whether those participating in the interactive art exhibition event engaged in better foot care after viewing the art. Thus, in terms of health literacy, health care innovation and exchange, whether the participants in the event are enabled to think further about foot care, health conditions in relation to reflexology, and to feel motivated to change their behaviour? I consider whether the dialogue that ensues among viewers in the gallery space plays a contributing role to illness prevention, health promotion and how the self-care of feet may contribute to a sense of wellness and well-being.
My thesis is that the art gallery event serves both as an artistic and a health promotion endeavour, demonstrated through the narratives of photography and interactive art. The liveness and performativity of the event (with two reflexologists present to conduct mini-taster sessions of individual client assessment during the exhibition) raises questions of how to evaluate the interaction and how to analyse the practical implications of the ideas that the exhibition is advancing. I consider the experiment from the perspective of both the academic and the complementary health therapist, particularly in relation to my role as a Senior Research Fellow at Nottingham Trent University, UK in the Narrative & Interactive Arts Department in the School of Art and Design, and in my role as a Reflexologist in private practice.

Moving Beyond the National Lung Screening Trial: Discussing Strategies for Implementation of Lung Cancer Screening Programs
Authors: Goulart Bernardo H.L. , Ramsey Scott D. 
Published: July 2013

Abstract
The National Lung Screening Trial (NLST) has sparked new interest in the adoption of lung cancer screening using low-dose computed tomography (LDCT). If adopted at a national level, LDCT screening may prevent approximately 18,000 lung cancer deaths per year, potentially constituting a high-value public health intervention. Before incorporating LDCT screening into practice, health care institutions need to consider the risks associated with LDCT screening and the impact of LDCT screening on health care costs, as well as other remaining areas of uncertainty, including the unknown cost-effectiveness of LDCT screening. This article will review the benefits and risks of LDCT screening in light of the results of the NLST and other randomized trials, it will discuss the additional health care costs associated with LDCT screening from the perspective of health care payers, and it will examine the published cost-effectiveness analyses of LDCT screening. A subsequent discussion highlights guideline recommendations for implementation strategies, the goals of which are to ensure that those eligible for LDCT screening derive the benefits while minimizing the risks of screening and avoiding an unnecessary escalation in screening-related costs. The article concludes by endorsing the use of LDCT screening in institutions capable of responsible implementation of screening in both medical and economic terms. The key elements of responsible implementation include the development of standardized screening practices, careful selection of screening candidates, and the creation of prospective registries that will mitigate current areas of uncertainty regarding LDCT screening.

Anticipating a Post-task Activity: The Effects on Accuracy, Complexity, and Fluency of Second Language Performance
Authors: Foster Pauline , Skehan Peter 
Published: July 2013

Abstract: The concept of focus on form has been influential in second language (L2) acquisition and pedagogy. One example of the implementation of focus on form is a post-task activity (e.g., anticipation of a public performance) that can selectively orient learners toward increased levels of accuracy. The present research proposes a new operationalization of a post-task activity, requiring L2 speakers, post-task, to transcribe some of their earlier task performance for both narrative and decision-making tasks. This study indicates that the predicted accuracy effect is obtained with both tasks, but so too is an effect of complexity for the decision-making task. Results are discussed in terms of the way L2 speakers allocate attention during task performance and how this allocation can be influenced by experimental conditions.
