Organized hypocrisy, organizational façades, and sustainability reporting

Abstract: Sustainability discourse is becoming ubiquitous. Still, a significant gap persists between corporate sustainability talk and practice. Prior research on corporate sustainability reporting has relied primarily on two competing theoretical framings, signaling theory and legitimacy theory, which often produce contradictory results regarding the significance and effects of such disclosures. Thus, despite this substantial body of research, the role that sustainability disclosures can play in any transition toward a less unsustainable society remains unclear. In an effort to advance our collective understanding of voluntary corporate sustainability reporting, we propose a richer and more nuanced theoretical lens by drawing on prior work in organized hypocrisy (Brunsson, 1989) and organizational facades (Abrahamson & Baumard, 2008; Nystrom & Strabuck, 1984). We argue that contradictory societal and institutional pressures, in essence, require organizations to engage in hypocrisy and develop facades, thereby severely limiting the prospects that sustainability reports will ever evolve into substantive disclosures. To illustrate the use of these theoretical concepts, we employ them to examine the talk, decisions, and actions of two highly visible U.S.-based multinational oil and gas corporations during the time period of significant national debate over oil exploration in the Alaskan National Wildlife Refuge. We conclude that the concepts of organizational facade and organized hypocrisy are beneficial to the sustainability disclosure literature because they provide theoretical space to more formally acknowledge and incorporate how the prevailing economic system and conflicting stakeholder demands constrain the action choices of individual corporations.

Head-worn displays: a review

Abstract: Head-worn display design is inherently an interdisciplinary subject fusing optical engineering, optical materials, optical coatings, electronics, manufacturing techniques, user interface design, computer science, human perception, and physiology for assessing these displays. This paper summarizes the state-of-the-art in head-worn display design (HWD) and development. This review is focused on the optical engineering aspects, divided into different sections to explore principles and applications. Building on the guiding fundamentals of optical design and engineering, the principles section includes a summary of microdisplay or laser sources, the Lagrange invariant for understanding the trade-offs in optical design of HWDs, modes of image presentation (i.e., monocular, biocular, and stereo) and operational modes such as optical and video see-through. A brief summary of the human visual system pertinent to the design of HWDs is provided. Two optical design forms, namely, pupil forming and non-pupil forming are discussed. We summarize the results from previous design work using aspheric, diffractive, or holographic elements to achieve compact and lightweight systems. The applications section is organized in terms of field of view requirements and presents a reasonable collection of past designs

Exploiting Open-Endedness to Solve Problems Through the Search for Novelty

Abstract: This paper establishes a link between the challenge of solving highly ambitious problems in machine learning and the goal of reproducing the dynamics of open-ended evolution in artificial life. A major problem with the objective function in machine learning is that through deception it may actually prevent the objective from being reached. In a similar way, selection in evolution may sometimes act to discourage increasing complexity. This paper proposes a single idea that both overcomes the obstacle of deception and suggests a simple new approach to open-ended evolution: Instead of either explicitly seeking an objective or modeling a domain to capture the open-endedness of natural evolution, the idea is to simply search for novelty. Even in an objective-based problem, such novelty search ignores the objective and searches for behavioral novelty. Yet because many points in the search space collapse to the same point in behavior space, it turns out that the search for novelty is computationally feasible. Furthermore, because there are only so many simple behaviors, the search for novelty leads to increasing complexity. In fact, on the way up the ladder of complexity, the search is likely to encounter at least one solution. In this way, by decoupling the idea of open-ended search from only artificial life worlds, the raw search for novelty can be applied to real world problems. Counterintuitively, in the deceptive maze navigation task in this paper, novelty search significantly outperforms objective-based search, suggesting a surprising new approach to machine learning.

Relationships Between Game Attributes and Learning Outcomes

Abstract: Games are an effective and cost-saving method in education and training. Although much is known about games and learning in general, little is known about what components of these games (i.e., game attributes) influence learning outcomes. The purpose of this article is threefold. First, we review the literature to understand the "state of play" in the literature in regards to learning outcomes and game attributes - what is being studied. Second, we seek out what specific game attributes have an impact on learning outcomes. Finally, where gaps in the research exist, we develop a number of theoretically based proposals to guide further research in this area.
