Income Distributions versus Lotteries Happiness, Response-Mode Effects, and Preference

This paper provides a comparative experimental study of risky prospects (lotteries) and income distributions. The experimental design consisted of multi?outcome lotteries and n?dimensional income distributions arranged in the shapes of ten distributions which were judged in terms of ratings and valuations, respectively. Material incentives applied. We found heavy response?mode effects, which cause inconsistent behavior between rating and valuation of lotteries and income distributions in more than 50% of all cases. This means that ethical inequality measures lack support in peoples? perceptions. In addition to classical preference reversals between generalized P?bets and $?bets we observed three additional patterns of preference reversal, two of which apply only to income distributions. Dominating Lorenz curves and Lorenz curves cutting others from below receive decidedly higher ratings (which implies risk and inequality aversion), but lower valuations. The transfer principle is largely violated. The rating of lotteries is a decreasing function of skewness, the rating of income distributions is a decreasing function of standard deviation. The valuation of lotteries is an increasing function of standard deviation and kurtosis, and the valuation of income distributions is an increasing function of standard deviation, skewness, and kurtosis. --Income Distribution,Lotteries,Income Happiness,Inequality and Risk Aversion,Ethical Inequality Measures,Preference Reversal

Bisimulations for Delimited-Control Operators

We present a comprehensive study of the behavioral theory of an untyped $\lambda$-calculus extended with the delimited-control operators shift and reset. To that end, we define a contextual equivalence for this calculus, that we then aim to characterize with coinductively defined relations, called bisimilarities. We consider different styles of bisimilarities (namely applicative, normal-form, and environmental) within a unifying framework, and we give several examples to illustrate their respective strengths and weaknesses. We also discuss how to extend this work to other delimited-control operators

The Library & Generative AI

A demonstration of several AI tools, including ChatGPT, ChatPDF, Consensus, and more. The focus of the session is on potential student uses of the tools and related library initiatives, so we address the limits of ChatGPT as an information source. Librarians can help students learn how to use these tools responsibly and provide leadership on campus as AI is integrated into assignments

Coordinating visualizations of polysemous action: Values added for grounding proportion

We contribute to research on visualization as an epistemic learning tool by inquiring into the didactical potential of having students visualize one phenomenon in accord with two different partial meanings of the same concept. 22 Grade 4-6 students participated in a design study that investigated the emergence of proportional-equivalence notions from mediated perceptuomotor schemas. Working as individuals or pairs in tutorial clinical interviews, students solved non-symbolic interaction problems that utilized remote-sensing technology. Next, they used symbolic artifacts interpolated into the problem space as semiotic means to objectify in mathematical register a variety of both additive and multiplicative solution strategies. Finally, they reflected on tensions between these competing visualizations of the space. Micro-ethnographic analyses of episodes from three paradigmatic case studies suggest that students reconciled semiotic conflicts by generating heuristic logico-mathematical inferences that integrated competing meanings into cohesive conceptual networks. These inferences hinged on revisualizing additive elements multiplicatively. Implications are drawn for rethinking didactical design for proportions. © 2013 FIZ Karlsruhe

Time is on my side : harnessing the power of automation for efficient archival workflows.

In the 21st century, the idea of utilizing technology to increase efficiency is nothing new. However, many librarians and archivists lack specialized training in computer programming, file management, and other advanced technological skills. Instead, our professional training focused on more traditional aspects of librarianship like the reference interview, collection development, and subject analysis. Although these remain important components of serving our users, learning new ways to streamline workflows can free up time we spend on automatable tasks and allow us more time to concentrate on specialized aspects of our work that only we as trained archivists and librarians can accomplish. Regardless of institutional resources, simple techniques can make a significant impact on processes and productivity. This article provides examples of how archivists successfully integrated automation techniques into their collection management workflows and illustrates the impact these techniques can have regardless of institutional resources

Knowledge modelling for integrating semantic web services in e-government applications

Service integration and domain interoperability are the basic requirements in the development of current service-oriented e-Government applications. Semantic Web and, in particular, Semantic Web Service (SWS) technology aim to address these issues. However, the integration between e-Government applications and SWS is not an easy task. We argue that a more complex semantic layer needs to be modeled. The aim of our work is to provide an ontological framework that maps such a semantic layer. In this paper, we describe our approach for creating a project-independent and reusable model, and provide a case study that demonstrates its applicability

Women in the outdoors: navigating fear and creating space for spiritual inspiration.

The purpose of this study was to examine the relationship between fear and spiritual inspiration for women in the outdoors. Specifically, this study looked at participants from SUNY Cortland’s Outdoor Education Practicum, a core course in the Recreation, Parks, and Leisure Studies Department that culminates with a two-week outdoor experience, with the goals of teaching outdoor skills and building community. This was a mixed-method study, with quantitative data collected according to pre(mid)post design and qualitative data coming from journal entries over a 5-day period. Testing was conducted using the Outdoor Situational Fear Inventory to measure fear, and the Nature Relatedness Scale to measure spiritual inspiration, and qualitative data from participants journals were analyzed for themes of fear, spirituality, and gender. A total of 85 male and female participants completed testing over two years of the course, in 2018 and 2019. It was concluded that the relationship between level of fear and spiritual inspiration for women in the outdoors, while not always significant, is meaningful. While female participants started out at significantly higher levels of fear than males, by the end of the course, the difference in fear level between genders was eliminated
