Are Distance Effects Really a Puzzle

SSRN Electronic Journal, 2009
In this paper, I use gravity equation with all the possible controls and a large bilateral panel data over 50 years and more than175 countries to estimate the distance effect from 1950 to 1999. An extensive search reveals some new results: different from previous finding that distance effects rose around the middle of the 20th century, distances ...

Effects of limited input distance constraints upon the distance geometry algorithm

Biopolymers, 1991
AbstractIn this paper we examine the distance geometry (DG) algorithm in the form used to determine the structure of proteins. We focus on three aspects of the algorithm: bound smoothing with the triangle inequality, the random selection of distances within the bounds, and the number of distances needed to specify a structure.

Effective Practices in Distance Education

Computers in the Schools, 2001
Distance education is changing the landscape of higher education and many faculty are now developing Web-based courses. This paper describes the lessons learned by the authors' experiences and research and offers a specific set of pedagogical and assessment strategies that they have found to be successful in online settings. The authors have found that

Inter‐Site Distance Effect in Electrocatalysis

Angewandte Chemie
AbstractThe inter‐site distance effect (ISDE) has gained significant attention in heterogeneous catalysis, challenging classical models that treat adjacent nonbonded sites as isolated. Recent studies demonstrate that these sites can exhibit long‐range cooperative interactions, enhancing reaction efficiencies.

Future events are far away: Exploring the distance-on-distance effect.

Journal of Personality and Social Psychology, 2014
Four dimensions of psychological distance (temporal, social, spatial, and probabilistic) have been widely studied. This research examines the distance-on-distance effect where an event that is close or distal along one dimension of psychological distance will be judged to be close or distal along other dimensions. For example, individuals will perceive

Feature selection with effective distance

Neurocomputing, 2016
Abstract As more features are introduced in pattern recognition and machine learning applications, feature selection remains a critically important task to find the most compact representation of data, especially in unsupervised learning scenarios without enough class labels.

How Effective Is Social Distancing?

SSRN Electronic Journal, 2020
We identify the dynamic effects of social distancing policy on reducing the transmission of the COVID-19 spread. We build a model that measures the relative frequency and geographic distribution of the virus growth rate and provides hypothetical infection distribution in the states that enacted the social distancing policy, where we control all time ...
