The Steady-State Growth Theorem: A Comment on Uzawa (1961)

This brief note revisits the proof of the Steady-State Growth Theorem, first provided by Uzawa (1961). We provide a clear statement of the theorem and a new version of Uzawa's proof that makes the intuition underlying the result more apparent.

Cumbria and the northern Pennines

Carboniferous rocks within the Cumbria and northern Pennines region are bound by the Maryport–Stublick–Ninety Fathom Fault System, which forms the northern boundary of the Lake District and Alston blocks (Fig. 12.1). In the Pennines, the succession occupies the Alston and Askrigg blocks and the intervening Stainmore Trough, a broadly east-west trending graben. Carboniferous strata also flank the Lake District High, occurring at outcrop in north Cumbria, Furness and Cartmel (south Cumbria) and the Vale of Eden, and in the subsurface in west Cumbria. The Askrigg Block succession is separated from that of the Craven Basin (Chapter 11), to the south, by the Craven Fault System

The Linking Gap in Negotiations

This paper investigates the concept of “the liking gap,” or the difference between how much someone perceives they are liked by another party and how much that other party actually likes them, specifically within the context of negotiations. Using data collected from simulated in-class negotiations during the Fall of 2020, this paper attempts to understand whether the party that “loses” a negotiation tends to have a larger or smaller liking gap than the party that “wins” the negotiation. It also investigates the direction of this gap, determining whether a win or loss impacts your likelihood to overestimate or underestimate how much your counterpart likes you. Analysis demonstrated that there is no significant correlation between negotiation outcome and liking gap, however, it did indicate that those who win an election tend to underestimate how much their counterparts like them following the negotiation’s conclusion. Since negotiations often take place in high-profile interactions and can affect relationships between high-ranking, powerful individuals, understanding the impact of a negotiation’s outcome can prove incredibly beneficial for relationship management over the long term

Lost in knowledge translation:Our shifting research landscape

In 2018 there is a new research modality. Research is increasingly produced by individuals and organizations not formally affiliated with academic institutions; based on funding that does not come from the public sphere; aligned with and intended to support advocacy perspectives and is designed for use by particular communities and agents. The new research modality presents challenges and opportunities. While all of these new agents in the research landscape are well educated and qualified to conduct research, in many cases they are operating outside of the traditional research environment and perhaps with a different set of “research cultural norms”. This new research modality in fact begs for a solution similar to that promoted within the health sciences field – a model of knowledge translation. A panel of researchers drawn from across the new research landscape will engage with information professionals to discuss six key questions.</p

Novel Distances for Dollo Data

We investigate distances on binary (presence/absence) data in the context of a Dollo process, where a trait can only arise once on a phylogenetic tree but may be lost many times. We introduce a novel distance, the Additive Dollo Distance (ADD), which is consistent for data generated under a Dollo model, and show that it has some useful theoretical properties including an intriguing link to the LogDet distance. Simulations of Dollo data are used to compare a number of binary distances including ADD, LogDet, Nei Li and some simple, but to our knowledge previously unstudied, variations on common binary distances. The simulations suggest that ADD outperforms other distances on Dollo data. Interestingly, we found that the LogDet distance performs poorly in the context of a Dollo process, which may have implications for its use in connection with conditioned genome reconstruction. We apply the ADD to two Diversity Arrays Technology (DArT) datasets, one that broadly covers Eucalyptus species and one that focuses on the Eucalyptus series Adnataria. We also reanalyse gene family presence/absence data on bacteria from the COG database and compare the results to previous phylogenies estimated using the conditioned genome reconstruction approach

Understanding vision: students’ use of light and optics resources

We present a qualitative study designed to examine how students construct an understanding of the human eye and vision from their knowledge of light and optics. As would be expected, vast differences are shown to exist between pre- and post-instruction students in terms of not only resource use, but also willingness to transfer their existing knowledge. However, we have found that appropriate scaffolding can facilitate resource activation and guide students to construct an understanding of vision and vision defects
