The reminiscence bump in autobiographical memory: An investigation of the life script hypothesis

Researchers have consistently found that older adults report a higher percentage of autobiographical memories for experiences that occurred between ages 15 and 30 compared to any other period of life. This reminiscence bump is evident for memories involving positive emotions but not for memories involving negative emotions. The life script hypothesis proposes that people share cultural knowledge for the types and timing of positive landmark events expected to occur over the life course and that this shared knowledge guides the retrieval of autobiographical memories. In a series of five studies, the valence (positive and negative) and expectedness (not surprising and surprising; expected and unexpected) dimensions of the life script account of the reminiscence bump were examined. In Study 1, college students reported positive and negative memories between the ages of 8 and 18 (corresponding to the ages where positive and negative memory distributions begin to diverge) that were either surprising or not surprising. In Studies 2 and 3, college students predicted and older adult recalled positive and negative memories from across the life span that were either surprising or not surprising. Finally, in Studies 4 and 5, college students predicted and older adults recalled memories that were highly expected and highly unexpected and rated these memories on positive and negative valence only after providing their descriptions. Inconsistent with life script predictions, memories cued by prompts for surprising and unexpected events demonstrated classic reminiscence bumps. The results show that positive memories are overrepresented between ages 15 and 30, but that a recently activated life script is not necessary to guide the memory search to this age period

Design and development of a virtual reality serious game with editable content

Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2020, Director: Inmaculada Rodrı́guez Santiago[This project is about the development and design of a Virtual Reality game to go along with the standard educational curriculum and make the activity of learning an even more fun experience. The game will be an escape room with trivia/multi answer questions introduced by the teacher that will condition the players to progress. The game was built in the Unity game engine using c#. A companion web app was built using Javascript and Firebase, to be used by the teachers to upload their open subject questions for the game. The project was built with scalability in mind to make the project a starter for other students so it is highly encouraged that any students on different paths (business, psychology, or other computer science students), adopt this project and build on top it.

Strategic trade in pollution permits

Markets for pollution have become a popular regulatory instrument. Yet these markets are often highly concentrated, which may lead to strategic behavior by all participants. In this article we investigate the implications of strategic trade in pollution permits. The permit market is developed as a strategic market game, where all firms are allowed to behave strategically and their roles as buyers or sellers of permits are determined endogenously with price-mediated trade. In a second stage, firms transact on a product market and we allow for a variety of market structures. Our framework establishes the endogenous determination of equilibrium price, market structure, and levels of exchange in the permit market

Contests with general preferences

This article investigates contests when heterogeneous players compete to obtain a share of a prize. We prove the existence and uniqueness of the Nash equilibrium when players have general preference structures. Our results show that many of the standard conclusions obtained in the analysis of contests - such as aggregate effort increasing in the size of the prize and the dissipation ratio invariant to the size of the prize — may no longer hold under a general preference setting. We derive the key conditions on preferences, which involve the rate of change of the marginal rate of substitution between a player’s share of the prize and their effort within the contest, under which these counter-intuitive results may hold. Our approach is able to nest conventional contest analysis — the study of (quasi-)linear preferences — as well as allowing for a much broader class of utility functions, which include both separable and non-separable utility structures

Interdependency modeling of supply chain risks incorporating game theoretic risks

Most of the current risk quantification techniques being applied in the field of Supply Chain Risk Management consider risk factors to be independent. This research considers risks as interdependent triggers, events and consequences. We propose a risk quantification framework based on Bayesian belief network modeling that is an effective method to capture the mentioned interaction between various risk factors. The conflicting incentives among stakeholders in a supply chain can jeopardize the success of a project and therefore, quantification of this category of risks named as 'Game theoretic risks' needs special consideration. We have assessed game theoretic risks in the development project of Boeing 787 aircraft. The game theoretic analysis captures uncertainty of the Tier-1 suppliers about the cost functions of each other and demonstrates that any uncertainty of information in a supply chain can adversely affect the intended outcome. Finally, we have designed a fair sharing partnership featuring continuous time domain and present value of money concept that aligns the conflicting incentives

The rhenium isotope composition of Atlantic Ocean seawater

The concentrations and isotopic compositions of rhenium are presented from seawater samples obtained from the primary station for the Bermuda Atlantic Time Series Study in the North Atlantic Ocean and from the 40oS UK GEOTRACES expedition in the South Atlantic Ocean. Salinity-normalized Re concentrations in both locations range between ∼6.8–7.7 ppt between 50–5000 m depth, consistent with previously published concentration data from the North Atlantic and North Pacific Oceans. Rhenium isotope values (expressed as δ187/185Re relative to NIST 3143) exhibit minimal variation around an average value of −0.17 ± 0.12‰ (n = 12, 2 S.D.), irrespective of water depth or water mass. These results confirm that the isotopic composition of perrhenate (ReO4−) in seawater is uniform. The new data establish a baseline for evaluating the isotopic mass balance of Re, and for future assessments of whether this global cycle can be disturbed by changes in seafloor redox and/or global weathering rates

Multiproxy reconstruction of oceanographic conditions in the southern epeiric Kupferschiefer Sea (Late Permian) based on redox-sensitive trace elements, molybdenum isotopes and biomarkers

The key drivers controlling the redox state of seawater and sediment pore waters in low energy environments can be inferred from redox-sensitive trace elements (RSTE), molecular biomarkers and trace metal isotopes. Here, we apply a combination these tools to the Upper Permian Kupferschiefer (T1) from the Thuringian Basin, deposited in the southern part of the semi-enclosed Kupferschiefer Sea. Enrichment patterns of the RSTEs molybdenum (Mo) and uranium (U) as well as biomarker data attest to the rapid development of euxinic conditions in basin settings during early T1 times, which became progressively less extreme during T1 deposition. The evolution of redox conditions in basinal settings, and the associated delay in the onset of euxinia at more shallow marginal sites, can be attributed to the interaction of sea-level change with basin paleogeography. Euxinia in the southern Kupferschiefer Sea did not lead to near-quantitative depletion of aqueous Mo, possibly due to short deepwater renewal times in the Thuringian Basin, low aqueous H2S concentrations, the continuous resupply of RSTE during transgression and declining burial rates of RSTEs throughout T1 times. 30 Drawdown of RSTE is, however, indicated for euxinic lagoon environments. Moreover, admixture of freshwater supplied to these lagoons by rivers strongly impacted on local seawater chemistry. The highest Mo-isotope compositions of ~1.70‰ in basin sediments allows a minimum Kupferschiefer Sea seawater composition of ~2.40‰ to be estimated. This composition is similar to the ~2.30‰ estimate for the Late Permian open ocean, and confirms a strong hydrographic connection between the epeiric Kupferschiefer Sea and the global ocean. The substantial variation in Moisotope signatures is paralleled by diagnostic shifts in biomarkers responding to oxygenation in different parts of the water column. Water column chemistry has been affected by variation in sea level, hydrodynamic restriction, riverine freshwater influx and evaporitic conditions in shallow lagoons. Elucidation of the relative role of each driving factor by a single geochemical proxy is not feasible but the complex scenario can be disentangled by a multiproxy approach

An introduction to imperfect competition via bilateral oligopoly

The aim of this paper is threefold. First, we provide a unified framework, by means of non-trivial examples, to compare the results obtained in simultaneous-move and sequential-move versions of bilateral oligopoly with the Cournot model and the Cournot-Walras approach. We also survey the main contributions on imperfect competition and strategic market games that are linked with our analysis. Secondly, we show how the bilateral oligopoly model can be used to study different kinds of oligopoly: symmetric oligopoly, where all agents act strategically; asymmetric oligopoly where only some agents act strategically; simultaneous oligopoly, where sellers and buyers make their choices without knowledge of others' decisions; and sequential oligopoly, where some agents move first. Thirdly, we focus on how the bilateral oligopoly model can clarify how either strategic or competitive behaviours may emerge endogenously depending on the fundamentals of the economy
