Driving Forces Behind Informal Sanctions This paper investigates the driving forces behind informal sanctions in cooperation games and the extent to which theories of fairness and reciprocity capture these forces. We find that cooperators’ punishment is almost exclusively targeted towards the defectors but the latter also impose a considerable amount of spiteful punishment on the cooperators. H...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
BACKGROUND When determinants of nutrition guidance practices for primary care physicians (PCPs) are identified, the key question remains: what is the mechanism of action? This knowledge is essential in order to understand how PCPs practice nutrition guidance. METHODS Mail questionnaires (result of focus-group discussions and in-depth interviews) were sent to a nationwide random sample of 1,00...
Prediction of structural forces of segmental tunnel lining using FEM based artificial neural network
To judge about the performance of designed support system for tunnels, structural forces i.e. peak values of axial and shear forces and moments are critical parameters. So in this study, at first a complete database using finite element method was prepared. Then, a model of artificial neural network (ANN) using multi-layer perceptron was developed to estimate lining structural forces. Sensitivi...
A B S T R A C T “Addiction” is a multifaceted complicated disorder with many interrelated causes, as well as environmental and genetic features. Several hereditary variables that have an effect on these features might work in together to influence vulnerability and the extent of being an addict. Molecular re-sequencing of the latest and formerly researched genes holds a crucial place with regar...
Background and Objective: Global macro trends on the one hand, and domestic trends and effective factors on the other, have put the future of the Iran's environment in a state of uncertainty with concern. In a complex and unpredictable environment, the use of scenario thinking (based on identifying and detecting future drivers and uncertainties) can provide tangible and comprehensible images of...
Understanding the processes of land use and land cover changes (LUCC) and the associated driving forces is important for achieving sustainable development. This paper presents the LUCC in Portugal at the regional level (NUTS II) from 1995 to 2010 and discusses the main driving forces and implications associated with these LUCC. The main objectives of this work are: (a) to quantify the land use ...
Vegetation patterns arise from the interplay between intraspecific and interspecific biotic interactions and from different abiotic constraints and interacting driving forces and distributions. In this study, we constructed an ensemble learning model that, based on spatially distributed environmental variables, could model vegetation patterns at the local scale. The study site was an alluvial f...
