A test of stress theory: relief workers in refugee camps

Disasters, 2011
The purpose of this paper is to apply a stress model drawn from the literature to the relief and social service workers who have been active in refugee camps for a prolonged period of time. Working in difficult environments, social service workers deliver essential services to refugee populations around the world.

Iterative RELIEF for Feature Weighting: Algorithms, Theories, and Applications

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2007
RELIEF is considered one of the most successful algorithms for assessing the quality of features. In this paper, we propose a set of new feature weighting algorithms that perform significantly better than RELIEF, without introducing a large increase in computational complexity.

Analytical theory for Bragg transmission surface relief gratings

Frontiers in Optics, 2003
Surface relief gratings can have high diffraction efficiencies in the “scalar” domain where the grating period is more than about ten times the illumination wavelength, as well as in the Bragg resonance domain where the grating period approaches the illumination wavelength and only three diffraction orders +1st, 0, -1st are nonevanescent. The resonance

Towards a theory of famine relief policy

Journal of Public Economics, 1987
Abstract This paper examines how famine mortality is related to the distribution of food consumption. A theoretical model is proposed of how individual survival chances are affected by changes in consumption. Uncertainty in survival prospects arises from the errors made by any observer in assessing health at given current consumption.

Judged humor, arousal, and the relief theory.

Journal of Personality and Social Psychology, 1968
The hypothesis that humor represents the sudden relief from strong affect was tested. Anxiety was used as the affect, and was varied among 3 groups of freshmen and sophomores by informing them of tasks they would be required to do, which supposedly would entail handling or extracting blood from white rats.

Effective grating theory for resonance domain surface-relief diffraction gratings

Journal of the Optical Society of America A, 2005
An effective grating model, which generalizes effective-medium theory to the case of resonance domain surface-relief gratings, is presented. In addition to the zero order, it takes into account the first diffraction order, which obeys the Bragg condition.

Ergodesign: synthesis of theory and practice using the example of a psychological relief room

Человек Общество Наука, 2023
This paper discusses the importance of using psychological relief rooms in enterprises. The role of ergodesign in such a space is considered, and the beneficial effects of the main elements of equipment are indicated. One of the possible programs for using the room is offered.

Feature Selection Using Cooperative Game Theory and Relief Algorithm

2016
With the advancements in various data mining and social network-related approaches, datasets with a very high feature—dimensionality are often used. Various information theoretic approaches have been tried to select the most relevant set of features, and hence bring down the size of the data. Most of the times these approaches try to find a way to rank

Lorenzo Ghiberti's Space in Relief: Method and Theory

The Art Bulletin, 1969
The investigation of Ghiberti's Third Commentary by Julius Schlosser in 19121 was extended in 1940 by G. Ten Doesschate,2 who concluded that the Third Commentary consisted almost entirely of notes and extracts from various ancient and medieval authorities. Where the text is concerned with optics, the sources are Alhazen, Avicenna, Witelo, John Peckham,
