Images that injure : pictorial stereotypes in the media
\"We are all aware of problematic stereotypes and prejudices regarding ethnicity, race, or gender; indeed, there are many laws to discourage such discriminatory behavior. The reality is that detrimental stereotypes in the media are so numerous and pervasive that they negatively affect the entire American population not just a minority of citizens. Not all damaging stereotypes are obvious. In fact, the pictorial stereotypes in the media that we don't notice could be the most harmful because we aren't even aware of the negative, false ideas they perpetrate. This book presents a series of original research essays on media images of groups including African Americans, Latinos, women, the elderly, the physically disabled, gays and lesbians, and Jewish Americans, just to mention a few. Specific examples of these images are derived from a variety of sources, such as advertising, fine art, film, television shows, cartoons, the Internet, and other media.\"--Front dust jacket flap.

Pseudo-Boolean optimisation for RobinX sports timetabling
We report on the development of Reprobate, a tool for solving sports timetabling problems in a subset of the RobinX format. Our tool is based around a monolithic translation of a sports timetabling instance into a pseudo-Boolean (PB) optimisation problem; this instance can be solved using existing pseudo-Boolean solvers. Once the tool has found a feasible solution, it can improve it using a second encoding that alters only the home/away pattern of games. We entered our tool into the International Timetabling Competition 2021. While it was effective on many instances, it struggled to cope with schedules involving large break constraints. However, among instances for which it could initially find a feasible solution, the combination of use of a portfolio of solvers, a range of variations on the encoding and the aforementioned local improvement process yielded an average reduction in solution cost of 23%.

Benefits and costs of ecological restoration: Rapid assessment of changing ecosystem service values at a U.K. wetland
Restoration of degraded land is recognized by the international community as an important way of enhancing both biodiversity and ecosystem services, but more information is needed about its costs and benefits. In Cambridgeshire, U.K., a long‐term initiative to convert drained, intensively farmed arable land to a wetland habitat mosaic is driven by a desire both to prevent biodiversity loss from the nationally important Wicken Fen National Nature Reserve (Wicken Fen NNR) and to increase the provision of ecosystem services. We evaluated the changes in ecosystem service delivery resulting from this land conversion, using a new Toolkit for Ecosystem Service Site‐based Assessment (TESSA) to estimate biophysical and monetary values of ecosystem services provided by the restored wetland mosaic compared with the former arable land. Overall results suggest that restoration is associated with a net gain to society as a whole of$199 ha−1y−1, for a one‐off investment in restoration of $ 2320 ha−1. Restoration has led to an estimated loss of arable production of$2040 ha−1y−1, but estimated gains of $ 671 ha−1y−1 in nature‐based recreation,$120 ha−1y−1 from grazing, $ 48 ha−1y−1 from flood protection, and a reduction in greenhouse gas (GHG) emissions worth an estimated$72 ha−1y−1. Management costs have also declined by an estimated $ 1325 ha−1y−1. Despite uncertainties associated with all measured values and the conservative assumptions used, we conclude that there was a substantial gain to society as a whole from this land‐use conversion. The beneficiaries also changed from local arable farmers under arable production to graziers, countryside users from towns and villages, and the global community, under restoration. We emphasize that the values reported here are not necessarily transferable to other sites. A detailed site‐scale assessment of benefits and costs of the conversion of arable land to wetland has been carried out in terms of ecosystem service values in the two states. It shows that restoration is associated with a net gain to society of $199 ha−1y−1 and that the balance of benficiaries shifts from the private to the public sector.

Photographic Coverage During the Persian Gulf and Iraqi Wars in Three U.S. Newspapers
The United States has engaged in military conflicts both honorable and questionable. Journalists have traveled to the front lines to produce stories and pictures both supportive and critical. A content analysis of images published in three U.S. newspapers during the start of the 1991 and 2003 wars with Iraq reveals that the military probably received the type of coverage it hoped for when it initiated the embedding program.

Analysis of MiniJava Programs via Translation to ML
MiniJava is a subset of the object-oriented programming language Java. Standard ML is the canonical representative of the ML family of functional programming languages, which includes F# and OCaml. Different program analysis and verification tools and techniques have been developed for both Java-like and ML-like languages. Naturally, the tools developed for a particular language emphasise accurate treatment of language features commonly used in that language. In Java, this means objects with mutable properties and dynamic method dispatch. In ML, this means higher order functions and algebraic datatypes with pattern matching. We propose to translate programs from one language into the other and use the target language's tools for analysis and verification. By doing so, we hope to identify areas for improvement in the target language's tools and suggest techniques, perhaps as used in the source language's tools, that may guide their improvement. More generally, we hope to develop tools for reasoning about programs that are more resilient to changes in the style of code and representation of data. We begin our programme by outlining a translation from MiniJava to ML that uses only the core features of ML; in particular, it avoids the use of ML's mutable references.

Which algorithm to select in sports timetabling?
Any sports competition needs a timetable, specifying when and where teams meet each other. The recent International Timetabling Competition (ITC2021) on sports timetabling showed that, although it is possible to develop general algorithms, the performance of each algorithm varies considerably over the problem instances. This paper provides an instance space analysis for sports timetabling, resulting in powerful insights into the strengths and weaknesses of eight state-of-the-art algorithms. Based on machine learning techniques, we propose an algorithm selection system that predicts which algorithm is likely to perform best when given the characteristics of a sports timetabling problem instance. Furthermore, we identify which characteristics are important in making that prediction, providing insights in the performance of the algorithms, and suggestions to further improve them. Finally, we assess the empirical hardness of the instances. Our results are based on large computational experiments involving about 50 years of CPU time on more than 500 newly generated problem instances.

Micropalaeontological dating of the basal Cretaceous section of DSDP Site 249, Leg 25, Mozambique Ridge: implications for the timing of the southern Atlantic–Indian Ocean connection
Tectonic models suggest the absence of a deep water connection on the Mozambique Ridge during early Neocomian time. These models imply the initiation of a deep water connection between the southern Atlantic and Indian oceans formed during Barremian–earliest Aptian times. However, previous biostratigraphic studies of the earliest deep water sediments on the Mozambique Ridge suggest that the basal section is Neocomian in age. Here, we present a new biostratigraphic analysis undertaken to test this tectonic model and determine the earliest age of deep water sedimentation on the Mozambique Ridge. Core samples from the Cretaceous interval 222.05–406.32 m (Cores 19–32) of DSDP Site 249, Leg 25, were sampled for calcareous nannoplankton and palynological analysis. Most of the sampling was concentrated on the Lower Cretaceous interval below 294 m. Our results indicate that the lower sedimentary section is no older than Barremian and therefore provides support for the age proposed by the tectonic models.

Commentary
[...]I am blessed with a loving wife, xtine, who in all ways is better than me and soon will be even betterer as the new editor of the Visual Communication Quarterly. Photographs were an essential part of two out of the sixteen published pieces, but as a visual communication scholar and advocate, I, naturally, always want additional pixels on the page.
