This paper introduces amodified formula for the fractal box counting dimension. Themethod is based on utilization of the probability distribution formula in the fractal box count. The purpose of this method is to use it for the discrimination of oil spill areas from the surrounding features, e.g., sea surface and lookalikes in RADARSAT-1 SAR Wide beam mode (W1) and Standard beam mode (S2) data ...

This article presents a thematic analysis of the research evidence on assessment feedback in higher education (HE) from 2000 to 2012. The focus of the review is on the feedback that students receive within their coursework from multiple sources. The aims of this study are to (a) examine the nature of assessment feedback in HE through the undertaking of a systematic review of the literature, (b)...

Several of the Major Transitions in natural evolution, such as the symbiogenic origin of eukaryotes from prokaryotes, share the feature that existing entities became the components of composite entities at a higher level of organisation. This composition of pre-adapted extant entities into a new whole is a fundamentally different source of variation from the gradual accumulation of small random...

human activities induced changes in land cover/use have extensive impacts on the landscape. in recent years, these changes had an increasingly growth due to irrational use of the natural resources in iran. hence, considering the negative effects of the inappropriate use of land and land-use change, understanding of the landscape changes over time is necessary to planning and implementation of s...

Multi-agent simulation was used to study several styles of leadership in small societies. Populations of 50 and100 agents inhabited a bounded landscape containing a fixed number of food sources. Agents moved about the landscape in search of food, mated, produced offspring, and died either of hunger or at a predetermined maximum age. Leadership models focused on the collection and redistribution...

The future of forests around the world is uncertain: forests are being cleared and the lands converted to other uses, while existing forests face many challenges from a variety of sources. The pressures on forests come from two usually opposing perspectives, timber production and wildlife conservation. This special issue volume attempts to bridge between these two disciplines and attempts to mo...

The design of the Nacadia® therapy garden is based on a model for evidence-based health design in landscape architecture (EBHDL). One element of the model is a diagnostic post-occupancy evaluation (DPOE), which has not previously been fully developed. The present study develops a generic DPOE for therapy gardens, with a focus on studying the effects of the design on patients' health outcomes. T...
