The “What” and “Why” of Goal Pursuits: Human Needs and the Self-Determination of Behavior

by Edward L. Deci, Richard M. Ryan , 2000
"... Self-determination theory (SDT) maintains that an understanding of human motiva-tion requires a consideration of innate psychological needs for competence, auton-omy, and relatedness. We discuss the SDT concept of needs as it relates to previous need theories, emphasizing that needs specify the nece ..."

We also discuss the relation of the psycho-logical needs to cultural

Thyroid Hormones Are Associated with Poorer Cognition in Mild Cognitive

by Dement Geriatr, Cogn Disord, Patrick Quinlan, Arto Nordlund, Karin Lind, Deborah Gustafson, Åke Edman A, Anders Wallin A , 2010
"... Background: Alterations in interrelated endocrine axes may be related to the pathogenesis of mild cognitive impairment (MCI) and dementia. Methods: Salivary cortisol before and after a 0.5-mg dexamethasone test, and serum levels of thyroid-stimulating hormone, total thyroxine (T 4), free T 4, total ..."

and executive functions. Results: The MCI group did not differ in basal levels of endocrine markers compared to controls. Among those with MCI, TT 3 levels were inversely associated with cognitive performance across all domains. After stratifying MCI cases according to TT 3 levels, those with relatively high TT

Tuning RED for Web Traffic

by Mikkel Christiansen, Kevin Jeffay, David Ott, F. Donelson Smith - in Proceedings of ACM SIGCOMM 2000 , 2000
"... We study the effects of RED on the performance of Web browsing with a novel aspect of our work being the use of a usercentric measure of performance — response time for HTTP request-response pairs. We empirically evaluate RED across a range of parameter settings and offered loads. Our results show t ..."

tuned to yield performance somewhat superior to FIFO, however, response times are quite sensitive to the actual RED parameter values selected, and (4) in such heavily congested networks, RED parameters that provide the best link utilization produce poorer response times. We conclude that for links

Clarifying achievement goals and their impact

by Heidi Grant, Carol S. Dweck - Journal of Personality & Social Psychology , 2003
"... The study of achievement goals has illuminated basic motivational processes, though controversy surrounds their nature and impact. In 5 studies, including a longitudinal study in a difficult premed course, the authors show that the impact of learning and performance goals depends on how they are ope ..."

Among performance goals, ability-linked goals predicted withdrawal and poorer performance in the face of challenge (but provided a “boost ” to performance when students met

Poorer aerobic fitness relates to reduced integrity of multiple memory systems

by Matthew B. Pontifex, Andrew C. Parks, Patrick C. O’neil, Adriel R. Egner, Joseph T. Warning, Karin A. Pfeiffer, Kimberly M. Fenn , 2014
"... Abstract Epidemiological investigations have revealed in-creases in the prevalence of sedentary behaviors in industrial-ized societies. However, the implications of those lifestyle choices and related cardiorespiratory fitness levels for memo-ry function are not well-understood. To determine the ext ..."

These data indicate that cardiorespiratory fitness may be important for the optimal function of neural networks under

Trade, Technology and the Environment: Why Do Poorer Countries Regulate Sooner?
