We consider the collection of all KenKen puzzles over the Klein four-group with certain symmetry conditions and classify all such puzzles by their number of solutions.

The past year has been difficult. Many friends and loved ones were lost during the coronavirus pandemic. All of us had to adjust, adapt, and learn new ways to live and work together while keeping ...healthy and safe in a virtual workspace. During this time, the NOAA Office of Ocean Exploration and Research, the Ocean Exploration Trust, and the Schmidt Ocean Institute continued their unique partnership to map, explore, and characterize the ocean while supporting goals of the blue economy. The partners advanced this mission by using virtual tools such as telepresence and new technologies to explore the deep ocean remotely, and most importantly, by drawing on the resilience and creativity of their people. NOAA's Office of Ocean Exploration and Research suspended ship operations in 2020.

A commonly occurring task in intelligence tests or recreational riddles is to “find the odd one out”, that is, to determine a unique element of a set of objects that is somehow special. It is ...somewhat arbitrary what exactly the relevant feature is that makes one object different. But once that is settled, the answer becomes obvious. Not so with a puzzle popularized by Tanya Khovanova to express her dislike for this type of puzzle. Here, it is a more complicated relation between the objects and the features that determines the odd object, because there is only one object that does not have a unique feature expression. This puzzle inspired me to look for even more complicated relations between objects, features and feature expressions that appear to be even more symmetric, but actually still single out a “special object”. This paper provides useful definitions, a theoretical basis, solution algorithms, and several examples for this kind of puzzle.
This paper proposes a novel approach to audio game design by introducing the concept of speech puzzles (spuzzles) to describe the utilisation of recorded voice for the creation of audio puzzles in ...ways that challenge players’ different listening modes. In the fields of audio games and audio-interactive applications, speech serves instructive, descriptive, narrative, and in some cases—in the form of hints or quizzes—gameplay purposes by addressing users through language. The suggested approach of spuzzles extends this potential by including, besides encoded meaning, the acoustic properties of sound, thus engaging the user’s causal and reduced listening modes in parallel with the semantic listening mode. An audio game consisting of four inherently different spuzzles was designed as proof of concept and tested by seven third-year students of Audiovisual Arts, who elaborated on their experience through a focus group semi-structured discussion. Despite their difficulty, the spuzzles were well accepted by most of the participants (5/7), whereas all participants agreed on their acoustic richness, need for concentration, and independence from pre-existing musical knowledge. Therefore, the authors suggest that the proposed design approach could serve as a paradigm for future research in the design of complex audio-based game mechanics.
We propose a novel generalized recursive smooth ambiguity model which permits a three-way separation among risk aversion, ambiguity aversion, and intertemporal substitution. We apply this utility ...model to a consumption-based asset-pricing model in which consumption and dividends follow hidden Markov regime-switching processes. Our calibrated model can match the mean equity premium, the mean risk-free rate, and the volatility of the equity premium observed in the data. In addition, our model can generate a variety of dynamic asset-pricing phenomena, including the procyclical variation of price-dividend ratios, the countercyclical variation of equity premia and equity volatility, the leverage effect, and the mean reversion of excess returns. The key intuition is that an ambiguity-averse agent behaves pessimistically by attaching more weight to the pricing kernel in bad times when his continuation values are low.
Puns, jokes, proverbs, riddles, play languages, verbal dueling, parallelism, metaphor, grammatical stretching and manipulation in poetry and song— people around the world enjoy these forms of speech ...play and verbal artistry which form an intrinsic part of the fabric of their lives. Verbal playfulness is not a frivolous pursuit. Often indicative of people’s deepest values and worldview, speech play is a significant site of intersection among language, culture, society, and individual expression. In this book, Joel Sherzer examines many kinds of speech play from places as diverse as the United States, France, Italy, Bali, and Latin America to offer the first full-scale study of speech play and verbal art. He brings together various speech-play forms and processes and shows what they have in common and how they overlap. He also demonstrates that speech play explores and indeed flirts with the boundaries of the socially, culturally, and linguistically possible and appropriate, thus making it relevant for anthropological and linguistic theory and practice, as well as for folklore and literary criticism.
