BACKGROUND Fatigue is a common and frequently observed complaint among older adults. However, knowledge about the nature and correlates of fatigue in old age is very limited. OBJECTIVE This study examined the relationship of functional indicators, psychological and situational factors and fatigue for 210 octogenarians and centenarians from the Georgia Centenarian Study. METHODS Three indica...
While a large number of studies have been reported in the literature with reference to the use of Regression model and Artificial Neural Network (ANN) models in predicting stock prices in western countries, the Chinese stock market is much less studied. Note that the latter is growing rapidly, will overtake USA one in 20 30 years time and thus becomes a very important place for investors worldw...
The need to monitor the environmental condition of ecosystems worldwide has resulted in a large number of potential bioindicators being proposed in the scientific literature. However, only a few have been validated at an adequate scale to monitor environmental problems and to solve management questions. Here we compiled a list of candidate seagrass indicators (n = 59) obtained from the literatu...
In human organism development is a very complex and highly regulated system that enables the functional balance of each organ in a whole body. Disorders and tumor micro-environment weaken host immune system that is not able to recognize the tumor as a unknown body and fight against its uncontrollable forces. Tumor avoids the immune system in a way that promotes immunosuppression and orientation...
Livestock and pasture imbalances are among the rangeland managers’ concerns. In this regard, decision makers were determined to reduce pressure on rangelands through alternative livelihoods, and multiple-use projects. Unfortunately, the multiple-use projects have not been implemented successfully in Golestan and Azadshahr provinces after five years of multifunctional project review service anno...
Assessing the performance of management is central to natural resource management, in terms of improving the efficiency of interventions in an adaptive-learning cycle. This is not simple, given that such systems generally have multiple scales of interaction and response; high frequency of nonlinearity, uncertainty, and time lags; multiple stakeholders with contrasting objectives; and a high deg...
This study investigates the effectiveness of an automatic system for detection of deception by individuals with the use of multiple indicators of such potential deception. Deception detection research in the information systems discipline has postulated increased accuracy through a new class of screening systems that automatically conduct interviews and track multiple indicators of deception si...
In multiple indicator models, there are several indicators for one trait–method unit. In the less restrictive model, there is one factor for all indicators belonging to the same trait–method unit. The correlations between these factors constitute a latent MTMM matrix. The correlation coefficients of this latent MTMM matrix are not distorted by measurement error and allow a more appropriate appl...
Classically, the exponent of a group is the least common multiple of the orders of its elements. This notion was generalized by Etingof and Gelaki to the context of Hopf algebras. Kashina, Sommerhäuser and Zhu later observed that there is a strong connection between exponents and Frobenius– Schur indicators. In this paper, we introduce the notion of twisted exponents and show that there is a si...
