Explaining intuitive difficulty judgments by modeling physical effort and risk

The ability to estimate task difficulty is critical for many real-world decisions such as setting appropriate goals for ourselves or appreciating others' accomplishments. Here we give a computational account of how humans judge the difficulty of a range of physical construction tasks (e.g., moving 10 loose blocks from their initial configuration to their target configuration, such as a vertical tower) by quantifying two key factors that influence construction difficulty: physical effort and physical risk. Physical effort captures the minimal work needed to transport all objects to their final positions, and is computed using a hybrid task-and-motion planner. Physical risk corresponds to stability of the structure, and is computed using noisy physics simulations to capture the costs for precision (e.g., attention, coordination, fine motor movements) required for success. We show that the full effort-risk model captures human estimates of difficulty and construction time better than either component alone

'Smart' design: greening the Total Product System

About the book: Since the Rio summit in 1992, the paradigm of corporate environmental responsibility has gradually and consistently extended beyond complying with increasingly stringent environmental regulation and taking up the proactive initiatives of a few world-class companies. Research indicates that the business and financial performance of companies may depend directly on socially and environmentally responsible business practices. Many world-class companies now realize that customers and other stakeholders do not distinguish between a company and its suppliers. As a result, greening the supply chain is an innovative idea which is fast gaining attention in the industry. Greening the Supply Chain is a compilation of important chapters written by a diverse set of international authors which incorporates a broad variety of perspectives.

Accelerating innovation development and scaling processes for agricultural transformation

At the 5th Global Science Conference on Climate-Smart Agriculture in Bali, CCAFS, IFAD and USDA-FAS organized the Side event “Accelerating innovation development and scaling climate-smart agriculture to drive a transformation in food systems”. High-level representatives of > 20 governments, research, donor, financial and policy institutions, civil society and private sectors discussed their previously shared insights and agreed to act as an “Insight Group” for further related CCAFS research and action. This Info Note summarizes the groups’ first findings, along with a short proposal for next steps

Financial literacy education in the United States: Exploring popular personal finance literature

As libraries work to define their roles within the global financial literacy education movement, it will serve them well to understand the popular literary component to this movement: the personal finance self-help genre. In this literature study, the author read 12 of the most popular books of this genre, as determined by simulations of likely Google searches, and conveys herein some of the beliefs and strategies these books may have imparted to library patrons. This study will benefit librarians by enhancing their understanding of the personal finance genre, conveying the genre’s interrelation to the current financial literacy movement, and even prompting librarians to question their own understanding regarding certain financial literacy components.Publisher does not allow open access until after publicatio
