The Many

Of the many visual characteristics of animals, countershading (darker pigmentation on those surfaces exposed to the most lighting) is one of the most common, and paradoxically one of the least well understood. Countershading has been hypothesized to reduce the detectability of prey to visually hunting predators, and while the function of a countershaded colour pattern was proposed over 100 years ago, the field has progressed slowly; convincing evidence for the protective effects of countershading has only recently emerged. Several mechanisms have been invoked for the concealing function of countershading and are discussed in this review, but the actual mechanisms by which countershading functions to reduce attacks by predators lack firm empirical testing. While there is some subjective evidence that countershaded animals match the background on which they rest, no quantitative measure of background matching has been published for countershaded animals; I now present the first such results. Most studies also fail to consider plausible alternative explanations for the colour pattern, such as protection from UV or abrasion, and thermoregulation. This paper examines the evidence to support each of these possible explanations for countershading and discusses the need for future empirical work.

The Impact

Abstract The purpose of this paper is to explore how sharecropping contracts are chosen over fixed-rent contracts. There are two concerning issues. First, theoretical explanation has been criticized for not providing a satisfactory answer to the question as to why share contracts are chosen. Second, among the existing empirical studies, there are great controversies about the impact of variance of output. Inspired by the latest insights from (Cheung, S. N. S. 2014. Economic Explanation. Hong Kong: Arcadia Press.), this paper not only provides an explanation for the choice of share contract that is suitable for empirical testing, but also solves the puzzle over variance of output.

Definition Of

Interest in news literacy inside and outside the academy has grown alongside related concerns about the quality of news and information available. Attempts to fully define, explicate and operationalize news literacy, however, are scattered. Drawing on literature across journalism and mass communication, we propose a definition of news literacy that combines knowledge of news production, distribution and consumption with skills that help audiences assert control over their relationship with news. We propose that knowledge and skills should be conceptualized across five domains: context, creation, content, circulation and consumption. This explication offers a clear, concise and cohesive path for research about news literacy, especially empirical testing to evaluate news literacy and its effectiveness in contributing to relevant behaviours. This framework also offers a consistent, yet flexible, approach to measuring news literacy across diverse contexts.

Deceptive Advertising

To be regulated by the FTC, an advertising claim must be both deceptive and material. Much attention and research has been directed to deception, but almost no study has been done on materiality. However, a recent case has highlighted the need for better understanding of this legal requirement. The authors explore the genesis and evolution of the materiality standard explain the pitfalls awaiting advertisers who try to prove their claims immaterial, and outline several considerations for empirical testing of advertisements.

Post Conflict

This article provides an overview of post-conflict justice (PCJ) as well as a detailed analysis of factors that impede or facilitate the implementation of mechanisms to address the atrocities of a conflict. Grounded in an extensive new dataset, developed over the past three years, covering all conflicts in Africa between 1946 and 2009, we extend previous research by including empirical testing of previously untested assumptions and variables impacting PCJ, most notably, the role of power, politics, economics, and geo-strategic interests at the state and international political levels as well as combining previously tested variables amongst and between each other. Further, the aspects of PCJ, including conflicts where mechanisms were not deployed are included in the analysis along with those coded as symbolic in nature. We conclude by discussing the pragmatic issues associated with testing the concept of realpolitik and policy implications based on our analysis.
