A comparative study of cannibalism in six populations of the calanoid copepod, Diaptomus leptopus (Forbes)
… life stages. Copepods are a typical example of the type of species which exhibit adult cannibalism of juvenile life stages. The scale of observation typically used in cannibalism studies may allow misinterpretation of the results. I used populations of Diaptomus leptopus from six independent …

The Arc Models.
The Arc Models are a set of three-dimensional, dynamic CGI representations of the primary pedagogical models of international trade theory. By characterizing economies according to their manufacturing, service, and agricultural/natural resource sectors, the Arc Models present a novel approach to …

Scale-Dependent Homogenization and Scaling Laws in Random Polycrystals
The framework of stochastic mechanics is employed to obtain scale-dependent bounds on the response of multifarious random polycrystals. In doing so, one infers the approach to the Representative Volume Element (RVE), the cornerstone of the separation of scales in continuum mechanics. The RVE is …

Taxonomic and Seasonal Variation Among Extant Hyracoids Based on Dental Microwear Texture Analysis
<p>A number of works have been published on habitats and diets of living hyraxes but much remains to be learned about the paleoenvironment contexts of the much larger, more dominant but now extinct forms of the order. Here, I analyze the dental microwear of modern hyraxes to assess dietary and …

Three essays on regional business cycle analysis
… activities are analyzed under the assumption of multi-level structure regional economic system. Compared to a single-level regional economic system, a multi-level regional economic system assumes that regional economies are exposed to a common factor that affects its sub-units. In the first …

Accelerated Alkali-Silica Reaction and Corrosion of Reinforcing Steel in Concrete: Application on Dry Casks
The durability is one of the main reasons making concrete the most abundantly consumed material in the world after water. However, severe exposure conditions and improper or low quality mixture designs can cause physical and chemical changes in concrete which lead to deterioration and premature …

Network identification via multivariate correlation analysis
… is to estimate the links between the elements of a system in a robust and reliable way. To address this issue, a statistical method based on Pearson’s correlation coefficient was proposed. The former inherits the versatility of the latter, declined in a general applicability to any kind of …

Analyzing variation in snow albedo across spatial scales of observation in the Alaskan boreal forest
… visible wavelengths. On average, more than 50% of the land area above 20° North latitude is snow covered by December. In a warming climate where temperatures are estimated to rise and less precipitation will fall as snow in high latitude regions, it is crucial to understand variation in snow …

Locating an Ottoman Port-City in the Early Modern Mediterranean: Izmir 1580-1780
Extant historiography considers Izmir as a case of early modern “boom town.” Its transformation from a mere pier for the provisions of Istanbul into a bustling trans-regional port-city, so the standard narrative goes, was due to mercantilist penetration by English and Dutch chartered companies at a …

Artificial Night Lighting and Anthropogenic Noise Alter Animal Activity, Body Condition, Species Richness, and Community Structure
… been found to affect wildlife in a wide variety of ways including behavioral changes, physiological responses, changes in species interactions, and altered community structure. Increased levels of light and noise pollution can originate from many sources including roads, energy development and …

Managing open habitats for species conservation : the role of wild ungulate grazing, small-scale disturbances, and scale
During the last decades, the global change of the environment has caused a dramatic loss of habitats and species. In Central Europe, open habitats are particularly affected. The main objective of this thesis was to experimentally test the suitability of wild megaherbivore grazing as a conservation …
