Cognitive architecture and instructional design

by John Sweller, Jeroen J. G. Van Merrienboer, Fred G. W. C. Paas - Educational Psychology Review , 1998
"... Cognitive load theory has been designed to provide guidelines intended to assist in the presentation of information in a manner that encourages learner activities that optimize intellectual performance. The theory assumes a limited capacity working memory that includes partially independent subcompo ..."

These structures and functions of human cognitive architecture have been used to design a variety of novel

Promoting the Use of End-to-End Congestion Control in the Internet

by Sally Floyd, Kevin Fall - IEEE/ACM TRANSACTIONS ON NETWORKING , 1999
"... This paper considers the potentially negative impacts of an increasing deployment of non-congestion-controlled best-effort traffic on the Internet.’ These negative impacts range from extreme unfairness against competing TCP traffic to the potential for congestion collapse. To promote the inclusion ..."

for identifying those flows suitable for bandwidth regulation. These approaches are to identify a high-bandwidth flow in times of congestion as unresponsive, “not TCP-friendly,” or simply using disproportionate bandwidth. A flow that is not “TCP-friendly ” is one whose long-term arrival rate exceeds that of any

Climate and atmospheric history of the past 420,000 years from the Vostok ice core,

"... Antarctica has allowed the extension of the ice record of atmospheric composition and climate to the past four glacial-interglacial cycles. The succession of changes through each climate cycle and termination was similar, and atmospheric and climate properties oscillated between stable bounds. Inte ..."

The ice-drilling project undertaken in the framework of a long-term collaboration between Russia, the United States and France at the Russian Vostok station in East Antarctica (78Њ S, 106Њ E, elevation 3,488 m, mean temperature −55 ЊC) has already provided a wealth of such information for the past two

Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,

by ] Richard Hackman , Grec R Oldham , 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

In either case, the potential for applying activation theory to the design of jobs may be limited mainly to those cases in which there are actively dysfunctional affective and behavioral

Unbundling Institutions

by Daron Acemoglu, Simon Johnson - JOURNAL OF POLITICAL ECONOMY , 2003
"... This paper evaluates the importance of “property rights institutions”, which protect citizens against expropriation by the government and powerful elites, and “contracting institutions”, which enable private contracts between citizens. We exploit exogenous variation in both types of institutions dri ..."

power. Using this instrumental variables approach, we find that property rights institutions have a first-order effect on long-run economic growth, investment, and financial development. Contracting institutions appear to matter only for the form of financial intermediation. A possible explanation

Determinants of long-term growth: a Bayesian Averaging of Classical Estimates (BACE) approach

by Xavier Sala-i-Martin, Gernot Doppelhofer, Ronald I. Miller , 2003
"... This paper examines the robustness and joint interaction of explanatory variables in cross-country economic growth regressions. It employs a novel approach, Bayesian Averaging of Classical Estimates (BACE), which constructs estimates as a weighted average of OLS estimates for every possible combina ..."

Of 67 explanatory variables we find 18 to be robustly partially correlated with long-term growth and another three variables

End-to-end available bandwidth: Measurement methodology, dynamics, and relation with TCP throughput

by Manish Jain, Constantinos Dovrolis - In Proceedings of ACM SIGCOMM , 2002
"... The available bandwidth (avail-bw) in a network path is of major importance in congestion control, streaming applications, QoS verification, server selection, and overlay networks. We describe an end-to-end methodology, called Self-Loading Periodic Streams (SLoPS), for measuring avail-bw. The basic ..."

Estimation and Inference in Large Heterogeneous Panels with a Multifactor Error Structure

by M. Hashem Pesaran , 2004
"... This paper presents a new approach to estimation and inference in panel data models with a multifactor error structure where the unobserved common factors are (possibly) correlated with exogenously given individual-specific regressors, and the factor loadings differ over the cross section units. The ..."

The laws of emotion

by Nico H. Frijda , 2007
"... ABSTRACT: It is argued that emotions are lawful phe-nomena and thus can be described in terms of a set of laws of emotion. These laws result from the operation of emotion mechanisms that are accessible to intentional control to only a limited extent. The law of situational meaning, the law of concer ..."
