Costs of reproduction due to resource allocation trade-offs have long been recognized as key forces in life history evolution, but little is known about their functional or genetic basis. Arabidopsis lyrata, a perennial relative of the annual model plant A. thaliana with a wide climatic distribution, has populations that are strongly diverged in resource allocation. In this study, we evaluated ...
Effects of causal networks on the structure and stability of resource allocation trait correlations.
Discovering the mechanisms by which genetic variation influences phenotypes is integral to understanding life-history evolution. Models describing causal relationships among traits in a developmental hierarchy provide a functional basis for understanding the correlations often observed among life-history traits. In this paper, we evaluate a developmental network model of life-history traits bas...
Ports are important to the US economy. This is particularly true with the Ports of Los Angeles and Long Beach (POLA/LB). Over 40% of all containers shipped in and out of the US flow through the two-port complex. In addition, the POLA/LB complex support large bulk cargo, tanker, and cruise ship operations. It is vital that these ports be protected from terrorist attack and/or from damage from na...
The classic Arrow–Debreu framework requires a very large number of specific securities to reach Pareto optimality. present paper shows that financial intermediation can play an important role in maintaining more parsimonious market while still obtaining In the developed, aggregate risk components individual risks are exchanged through highly reduced set nonspecific securities, idiosyncratic ins...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
Dependence structures of multiple risks play an important role in optimal allocation problems for insurance, quantitative risk management, and finance. However, in many existing studies on these problems, risks or losses are often assumed to be independent or comonotonic or exchangeable. In this paper, we propose several new notions of dependence to model dependent risks and give their characte...
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
This study aims to determine, explain and analyze the effect of asset allocation policies risk levels on performance Islamic mutual funds in Indonesia (Period 2016-2018). The independent variable this is Asset Allocation Policy Risk Level, while dependent Performance Sharia Mutual Funds. sample selection technique used purposive sampling 10 samples funds. method calculate Sharpe Ratio. quantita...
We examined the effects of life-history variables on risk-taking propensity, measured by subjective likelihoods of engaging in risky behaviors in five evolutionarily valid domains of risk, including between-group competition, within-group competition, environmental challenge, mating and resource allocation, and fertility and reproduction. The effects of life-history variables on risk-taking pro...
