We specify a system of equations that fully reflects the supply and demand sides of the market for agricultural open space at equilibrium. Although simple, the system is exceedingly flexible and allows for household and parcel heterogeneity. We derive an empirical model directly from the structural equations and contrast this using a simulated landscape with the econometric specification most o...
Forest planning is a major issue for future development of regions, and landscape changes reflect to a large extent land-use/cover patterns related to economic and option's values as driving forces. Managing for reducing variability may have high costs of stability or resilience. Decision theory relies on maximizing an average or expected value of a preference pattern expressed by utility funct...
In this paper, we investigate whether people's knowledge of the past influences their preferences and values towards future landscape change. "Knowledge of the past" is one aspect of the information set held by individuals, and a well-established finding in economics is that changes in information can change preferences and values. The particular aspects of knowledge of the past we work with he...
In BP models with hundreds of fluxes, we compute the effects of cosmological dynamics on the probability distribution of landscape vacua. Starting from generic initial conditions, we find that most fluxes are dynamically driven into a different and much narrower range of values than expected from landscape statistics alone. Hence, cosmological evolution will access only a tiny fraction of the v...
We demonstrate a calculated alpha-helix peptide folding energy landscape which accurately simulates the first experimentally measured alpha-helix melting energy landscape. We examine a 21-amino acid, mainly polyalanine peptide and calculate the free energy along the Psi Ramachandran angle secondary folding coordinate. The experimental free energy landscape was determined using UV resonance Rama...
In the recent century,Tehran has been confronted with urban sprawl and rapid population growth that have caused urban landscape transformation, whichis different in various parts of Tehran based on specific economic, cultural and social situations. What is important in this essay is the human perception of their landscape in this process of transformation; therefore, the purpose is analyzing la...
There is increasing awareness of the need to monitor trends in our constantly changing agricultural landscapes. Monitoring programmes often use remote sensing data and focus on changes in land cover/land use in relation to values such as biodiversity, cultural heritage and recreation. Although a wide range of indicators is in use, landscape aesthetics is a topic that is frequently neglected. Ou...
This study analyzed the landscape pattern changes, the dynamics of the ecosystem service values (ESVs) and the spatial distribution of ESVs from 1995 to 2005 in Guangzhou, which is the capital of Guangdong Province and a regional central city in South China. Remote sensing data and geographic information system techniques, in conjunction with spatial metrics, were used to facilitate the analysi...
Use and characteristics of the minor rural road network have changed dramatically in West-European intensive agricultural landscapes. These changes are caused by modern agriculture, by changing values of the road’s verges and by the multifunctionalization of the rural landscape. Changing the network, conventional farming practices often decrease landscape ecological stability. These problems ca...
Fitting protein-folding free energy landscape for a certain conformation to an NK fitness landscape.
The NK fitness landscape is a mathematical landscape model with a parameter k that governs the degree of ruggedness of the landscape. We presented a procedure to fit a given landscape to the NK fitness landscape by introducing the "apparent k-value"k(app). In this paper, we defined the protein free energy (DeltaG) landscape in amino acid sequence space, where DeltaG is the folding free energy f...
