Democratic simple majority voting is perhaps the most widely used method of group decision making in our time. Standard theory, based on “instability” theorems, predicts that a group employing this method will almost always fail to reach a stable conclusion. There is one case that the classic instability theorems do not treat: an even number of voters in 2 dimensions. We resolve this remaining ...
A global Slowdown, rising oil prices, and monetary tightening in industrial countries may lead to net capital outflows which accentuate high ratios of short-term to total external debt. This paper focuses on finding consistent indicators of financial instability. Knowledge of these indicators should assist attempts to implement institutional financial reform and improve an economy's resilien...
In this paper, the collisional filamentation instability of an electron beam-weakly magnetized and ionized plasma has been investigated in the presence of background plasma, using the fluid description. By describing the equilibrium configuration in the presence of binary collision terms between charged and neutral particles and using the local approximation method, the dispersion relation (DR)...
Exchange rate instability brings about significant changes in the domestic and foreign sectors that can impose negative effects on the whole economy. The present study investigates the effect of exchange and inflation rate instability on the lending behavior of Iranian banks by using data of the 10 banks over the time period 1382-1397(2003-2018). To do this, at first, a GARCH(1,1) of the exchan...
Among agricultural products in Iran, pistachio is one of the major export products that can produce foreign currency. The present study evaluated factors affecting pistachio export earnings instability and its effect on agricultural export during the studied period. For this purpose, export earnings instability index was calculated using "average absolute difference between export earnings and ...
The presence of van der Waals (vdW) force can lead to mechanical instability in freestanding nano-scale actuators. Most of the previous researches in this area have exclusively focused on modeling the instability in actuators with one actuating components. While, less attention has been paid to actuators consist of two actuating components. Herein, the effect of the vdW force on the instability...
most theories in social sciences have aspects of causality, but understanding the causes of social phenomena is not possible through statistical correlation tests. to overcome this problem, fuzzy qualitative comparative analysis was developed to identify the cause of social phenomena. having qualitative roots, this method tests the necessary and sufficient causes for the emergence of a social p...
abstract background: the polymorphic variants at codon 72 of the p53 gene, encoding either proline or arginine at residue 72, produce marked change in the structure of p53. from the evidence that the dnamismatch repair system and p53 interact to maintain genomic integrity, we hypothesized that the codon 72 variation may influence the prevalence of microsatellite instability a feature of malig...
objective(s) the main objective of this study was to investigate the status of chromosome stability in 3 human-mouse hybridoma cell lines over a period of time in various passages. materials and methods metaphase spreads from 3 human-mouse cell lines (hf2x653, spmo-4 and f3b6) that had been cultured in 4 successive passages, from 1 to 4 weeks, were prepared and analyzed. metaphase chromosomes s...
purpose ankle sprain is one of the most common injuries among athletes and instability and injury to this joint is responsible for long time loss of physical and recreational activity. also, it can impose high costs to sport teams. prevention of this injury is an important concern of practice and rehabilitation. one way of reducing the possibility of ankle joint injury is using an ankle orthosi...
